Answer:
1.041g is the maximum sigle dose for the person
Explanation:
The maximum dose for acetaminophen is 15.0mg / kg of body weight for adults
To find the maximum single dosage for a person who weighs 153lb we must convert the lb to kg (1lb = 0.4536kg):
153lb * (0.4536kg / 1lb) = 69.4kg is the mass of the person
As the maximum dose is 15.0mg / kg, the dose of the person is:
69.4kg * (15.0mg acetaminophen / kg) =
1041mg = 1.041g is the maximum sigle dose for the personFor every pound a company spends on advertising, it spends £0,75 on its website. Express the

0.38 L of HNO3 is titrated to equivalence using 0.14 L of 0.2 MNaOH. What is the concentration of the HNO3HNO3
Answer:
0.074M is concentration of the HNO₃ solution
Explanation:
The reaction of neutralization of nitric acid, HNO₃ with NaOH is:
HNO₃ + NaOH → H₂O + NaNO₃
Where 1 mole of nitric acid reacts per mole of NaOH
Based on the chemical reaction, the moles of NaOH at equivalence point are equal to moles of HNO₃ presents in the solution. With the moles and the volume we can find molarity as follows:
Moles NaOH = Moles HNO₃:
0.14L * (0.2mol NaOH / L) = 0.028mol NaOH = 0.028mol HNO₃
Molarity:
0.028mol HNO₃ / 0.38L =
0.074M is concentration of the HNO₃ solutionWhat is the edge length of a 369-g iron cube?(The density of iron is 7.86 g/cm3, and the volume of a cube is equal to the edge length cubed.)
Answer:
edge length = 3.61 cm
Explanation:
Givens
m = 369 gm
d = 7.86 gm / cm^3
v = ?
Formula
v = m / d
Solution
v = 369 / 7.86
v = 46.95 cm^3
============
That's not the answer. You must take the cube root of the volume
side = cube root (46.95)
side = 3.61 cm
The Edge length of the iron cube will be "3.61 cm".
Given values,
Weight of iron cube,
m = 369 g
Density of iron,
d = 7.86 g/cm³
The volume of iron cube will be:
→ [tex]V = \frac{m}{d}[/tex]
[tex]= \frac{369}{7.86}[/tex]
[tex]= 46.95 \ cm^3[/tex]
As we know that the volume of cube is "[tex]a^3 \ cm^3[/tex]".
hence,
→ [tex]a^3 = 46.95 \ cm^3[/tex]
or,
→ [tex]a = (46.95 \ cm^3)^{\frac{1}{3} }[/tex]
[tex]= 3.61 \ cm[/tex]
Thus the above answer is correct.

Chlorhexidine gluconate is available in different products in concentrations of 4% w/v and 0.12% w/v. How many milliliters of the more dilute product may be prepared from each fluidounce of the more concentrated product
Answer:
From each fluidounce, 985.78 milliliters of the more dilute product can be produced.
Explanation:
From the given information:
4% w/v = 4g of solute in 100 mL of solution
0.12% w/v = 0.12g of solute in 100 mL of solution
Since 1 fluidounce = 29.5735 ml
∴
100 mL of solution contains 4g of solute
29.95735 ml will have [tex]\dfrac{4}{100} \times 29.5735[/tex]
= 1.18294g solute
Thus, 1 fluidounce contains 1.18294g solute
So, for the dilute solution, 0.12 g solute yields 100 mL solution
∴ 1.18294g will have [tex]\dfrac{100}{0.12} \times 1.18294[/tex]
= 985.78 ml

Which element is represented by the following:
1s22s22p63s23p64s23d104p1?
Write the symbol.
Answer:
Gallium (Ga)
Explanation:
Gallium (Ga) is the element which is represented by the given electron configuration since the total number electron is 31.
A material that cannot be destroyed chemically is referred to as a chemical element. Although chemical processes cannot modify an atom, nuclear reactions can create new elements. The quantity of protons an element has defines it. An element's atoms all contain the same amount of protons, but its electron and neutron counts might vary. Ions are produced by altering the electron to proton ratio, whereas isotopes are produced by altering the neutron count. Since there are 31 total electrons in the universe, gallium (Ga) gets the element that is denoted by the specified electron configuration.

Answer:
16.14 liter
Explanation:
The tank capacity of a car is a measure of the amount of gallons or liters of liquid a tank (of any shape e.g. rectangular, cylindrical) can hold at maximum due to its volume. The S.I unit of the tank capacity is the m³, but it can be measured in liters, gallons and any other unit of volume.

A pair of students standard a sodium hydroxide solution using KHP and obtain the following concentrations: 0.1028 M, 0.1031 M, 0.1200 M, 0.1030 M and 0.1026 M. The students suspect that 0.1200 M is an outlier. Is 0.1200 M an outlier and what is the average concentration of the sodium hydroxide solution
Answer:
0.1200M is an outlier.
Average = 0.1063M
Explanation:
An outlier is defined as a value that is atypical based on the other observations.
We can define an outlier as a value that is out of the average ± Standard desviation.
The average of the values is:
(0.1028 M + 0.1031 M + 0.1200 M + 0.1030 M + 0.1026 M) / 5
Average = 0.1063MComputing the standard desviation, σ:
σ = 0.0077
The interval of accepted values is between:
0.1063 + 0.0077 = 0.1140M
0.1063 - 0.0077 = 0.0986M
As 0.1200M is out of this intercal, this value is an outlier
The definition of outlier depends of the author and the values you are studying.

how to solve stoichiometry problem in a synthesis reaction with iron metal and oxygen gas, what mass of iron metsl is required to produce 456.0g of ferric oxide?
Answer:
319.2 g of iron metal
Explanation:
We'll begin by writing the balanced equation for the reaction between iron (Fe) and oxygen (O₂) to produce ferric oxide (Fe₂O₃). This is illustrated below:
4Fe + 3O₂ —> 2Fe₂O₃
Next, we shall determine the mass of Fe that reacted and the mass of Fe₂O₃ produced from the balanced equation. This can be obtained as follow:
Molar mass of Fe = 56 g/mol
Mass of Fe from the balanced equation = 4 × 56 = 224 g
Molar mass of Fe₂O₃ = (56×2) + (16×3)
= 112 + 48
= 160 g/mol
Mass of Fe₂O₃ from the balanced equation = 2 × 160 = 320 g
SUMMARY:
From the balanced equation above,
224 g of Fe reacted to produce 320 g of Fe₂O₃.
Finally, we shall determine the mass of iron metal, Fe, required to produce 456 g of ferric oxide, Fe₂O₃. This can be obtained as follow:
From the balanced equation above,
224 g of Fe reacted to produce 320 g of Fe₂O₃.
Therefore, Xg of Fe will react to produce 456 g of Fe₂O₃ i.e
Xg of Fe = (224 × 456)/320
Xg of Fe = 319.2 g
Thus, 319.2 g of iron metal, Fe is required to produce 456 g of ferric oxide, Fe₂O₃.

A carbon dioxide gas is molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas.
When sound waves move through a medium, in what direction to do the particles in the medium move?
A sample of an unknown compound is vaporized at 150.°C . The gas produced has a volume of 960.mL at a pressure of 1.00atm , and it weighs 0.941g . Assuming the gas behaves as an ideal gas under these conditions, calculate the molar mass of the compound.
Answer:
34.02 g.
Explanation:
Hello!
In this case, since the gas behaves ideally, we can use the following equation to compute the moles at the specified conditions:
[tex]PV=nRT\\\\n=\frac{1.00atm*0.960L}{0.08206\frac{atm*L}{mol*K}*(150+273)K} =0.0277mol\\\\[/tex]
Now, since the molar mass of a compound is computed by dividing the mass over mass, we obtain the following molar mass:
[tex]MM=\frac{0.941g}{0.0277mol} \\\\MM=34.02g/mol[/tex]
So probably, the gas may be H₂S.

A 3.45 L container has a pressure of 2.14 atm and contains 0.461 mol of gas. What is the temperature inside the container?
100 points!!
Answer:
the temperature of gas inside the container is 195.2 K.
Explanation:
Given;
volume of gas in the container, V = 3.45 L
pressure of gas in the container, P = 2.14 atm
number of gas moles, n = 0.461 mol
The temperature of gas inside the container is calculated as;
[tex]PV = nRT\\\\T = \frac{PV}{nR}[/tex]
where;
R is gas constant = 0.08205 L.atm/mol.K
[tex]T = \frac{2.14 \ \times \ 3.45}{0.461 \ \times \ 0.08205} \\\\T = 195.2 \ K[/tex]
Therefore, the temperature of gas inside the container is 195.2 K.
