Pure silver has a brilliant white metallic luster. How many moles of silver, Ag, are in 7.54 × 1023 atoms of silver?

Answers

The number of moles of silver, Ag, that are in 7.54 × 10²³ atoms of silver is 1.25 moles

From the question,

We are to determine the number of moles of silver, Ag, that are present in 7.54 × 10²³ atoms of silver

From the formula

[tex]Number\ of\ moles =\frac{Number\ of\ atoms}{Avogadro's\ constant}[/tex]

Avogadro's  constant = 6.022 × 10²³  atoms mol⁻¹

and

From the given information

Number of silver atoms = 7.54 × 10²³ atoms

Putting the parameters into the formula, we get

Number of moles of silver present = [tex]\frac{7.54\times 10^{23} }{6.022\times 10^{23}}[/tex]

Number of moles of silver present = 1.2520757 moles

Number of moles of silver present ≅ 1.25 moles

Hence, the number of moles of silver, Ag, that are in 7.54 × 10²³ atoms of silver is 1.25 moles

An hibernating bear accumulates 25 kg of a triglyceride (846 g/mol) comprising the following fatty acids: C16, C17 and C18∆9. How many grams of β-hydroxybutyrate (104 g/mol) can the bear produce from this triglyceride during its hibernation?

Answers

The quantity of β-hydroxybutyrate the bear can produce

during hibernation is 3,073.30grams.

Hibernation is defined as the period of less activity by animals to conserve energy to survive coarse weather conditions.

A typical example of an animal that hibernates is the bear.

From the question, a bear is able to accumulate 25kg (25000grams) of triglyceride.

To calculate quantity of β-hydroxybutyrate that would be produced from 25kg triglyceride;

846g of triglyceride = 104grams of β-hydroxybutyrate

25000g of triglyceride = x grams

(Cross multiple to solve for x grams)

X = 104 × 25000/846

[tex]x = \frac{104 \times 25000}{846} [/tex]

[tex]x = \frac{2600000}{846} [/tex]

[tex]x = 3073.30grams[/tex]

Therefore, the quantity of β-hydroxybutyrate the bear can produce during hibernation is 3,073.30grams.

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity of amount of substance. It measure the number of elementary entities of a given substance that are present in a given sample. There are so many formula for calculating mole.

we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number

mole =given number of atoms ÷ 6.022×10²³(Avogadro number)

given number of atoms of MgCl[tex]_2[/tex]= 7.78 x 10²⁴

Substituting the values

mole= 7.78 x 10²⁴÷ 6.022×10²³

mole = 0.49moles of  MgCl[tex]_2[/tex]

A) tides and waves.

The phenomena which  wind causes  are waves and surface currents.

What are surface  currents?

Surface currents are caused by  winds  which blow over the ocean water and result in creation of waves. Surface currents  are horizontal streams of water which are capable of  flowing thousands of kilometers and can reach great depths.

Surface currents play a major role in determining the climate all over the world. They are influenced by three major factors 1) overall global wind patterns 2)rotation of earth 3)shape of ocean basins . When a surface  current collides with the land it  changes the direction of currents.

Because of surface currents the global climate has warmer water  from equator to the cooler parts of the ocean  as they transfer heat energy.

Answers

Answer:

In the final solution, the concentration of sucrose is 0.126 M

Explanation:

The number of moles of solute in the volume taken from the more concentrated solution will be equal to the number of moles of solute in the diluted solution. Then, the concentration of the first solution can be calculated using the following equation:

Ci · Vi = Cf · Vf

Where:

Ci = concentration of the original solution

Vi = volume of the solution taken to prepare the more diluted solution.

Cf = concentration of the more diluted solution.

Vf = volume of the more diluted solution.

For the first dillution:

26.6 ml · 2.50 M = 50.0 ml · Cf

Cf = 26.6 ml · 2.50 M / 50.0 ml

Cf = 1.33 M

For the second dilution:

16.0 ml · 1.33 M = 45.0 ml · Cf

Cf = 16.0 ml · 1.33 M / 45.0 ml

Cf = 0.473 M

For the third dilution:

20.0 ml · 0.473 M = 75.0 ml · Cf

Cf = 20.0 ml · 0.473 M / 75.0 ml

Cf = 0.126 M

In the final solution, the concentration of sucrose is 0.126 M

What is the molarity of aqueous lithium bromide if 25.0 mL of LiBr reacts with 10.0 mL of 0.250 M Pb(NO 3) 2

Answers

The molarity of aqueous lithium bromide, LiBr solution is 0.2 M

We'll begin by calculating the number of mole of Pb(NO₃)₂ in the solution.

Volume = 10 mL = 10 / 1000 = 0.01 L Molarity of Pb(NO₃)₂ = 0.250 MMole of Pb(NO₃)₂ =?

Mole = Molarity x Volume

Mole of Pb(NO₃)₂ = 0.25 × 0.01

Mole of Pb(NO₃)₂ = 0.0025 mole

Next, we shall determine the mole of LiBr required to react with 0.0025 mole of Pb(NO₃)₂

Pb(NO₃)₂ + 2LiBr —> PbBr₂ + 2LiNO₃

From the balanced equation above,

1 mole of Pb(NO₃)₂ reacted with 2 mole of LiBr.

Therefore,

0.0025 mole of Pb(NO₃)₂ will react with = 2 × 0.0025 = 0.005 mole of LiBr

Finally, we shall determine the molarity of the LiBr solution

Mole = 0.005 mole Volume = 25 mL = 25 / 1000 = 0.025 L Molarity of LiBr =?

Molarity = mole / Volume

Molarity of LiBr = 0.005 / 0.025

Molarity of LiBr = 0.2 M

Where M are the molarities of the solutions and V are the volumes of the solutions.

We want to determine the volume of a 2.903 M NaOH solution to mix in order to produce 500.0 mL of a 0.3344 M solution.

Substitute and solve for V₁:

[tex]\displaystyle \begin{aligned} (2.903 \text{ M})V_1 & = (0.3344 \text{ M})(500.0 \text{ mL}) \\ \\ V_1 & = 57.60\text{ mL} \end{aligned}[/tex]

Define atomic numbers and mass numbers

Answers

Atomic numbers is the number of a chemical element in the periodic table and the mass number is the total number of protons and neutrons in an atom

Answer:

1). Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (e.g., all atoms with six protons are carbon atoms); the number of protons in an atom is called the atomic number.

2) In contrast, the number of neutrons for a given element can vary. Forms of the same atom that differ only in their number of neutrons are called isotopes.

3) Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

The gas in a 250. mL piston experiences a change in pressure from 1.00 atm to 2.25 atm. What is the new volume (in mL) assuming the moles of gas and temperature are held constant?

Answers

Answer:

111.11 mL

Explanation:

Since the moles of gas and temperature are held constant the new volume can be found by using the formula for Boyle's law

[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

From the question

P1 = 1 atm

P2 = 2.25 atm

V1 = 250 mL

We have

[tex]V_2 = \frac{250 \times 1}{2.25} = \frac{250}{2.25} \\ = 111.1111111...[/tex]

We have the final answer as
