What mass of ammonium nitrate
is needed to dissolve in 995 g of
water to make a 1.50 m solution?

Answers

Answer:

=> 119.4597 g

Explanation:

From our question, we have been provided with the molarity of the resultant solution.

We know that, molarity of a solution is contained in 1 L or 1000 cm³ of solution.

Hence we have 1.50 moles in 1000 cm³.

Also, we know that, 1 cm³ equivalent to 1 g for water.

Thus, from our question we have 995 cm³ of water.

Lets now solve our problem;

1.5 moles are contained in 1000 c

x moles are contained in 995 cm³

Cross multiply

[tex]x \: moles \: = \frac{(995 {cm}^{3} \times 1.5 \: moles )}{(1000 {cm}^{3} )} \\ = \frac{1492.5 \: moles}{1000} \\ = 1.4925 \: moles[/tex]

1.4925 moles of NH4NO3 are required to be dissolved in water.

To find the mass of solute (NH4NO3) we use the formula;

Mass = RFM (Relative Formula Mass) x Number of moles

[tex] = 80.04 \: \frac{g}{mol} \times1.4925 \: mol \\ = 119.4597 \: g [/tex]

Therefore the mass of NH4NO3 needed to be dissolved in 995 g of water is 119.4597 g

Convert from moles to particles 6.02x1023 particles 1 mole Question 2. 2.7 moles of lithium Question 3. 1.8 moles of sodium chloride​

Answers

Considering the definition of Avogadro's number:

the number of molecules of lithium is 1.62621×10²⁴ molecules.the number of molecules of sodium chloride is 1.08414×10²⁴ molecules.

Definition of Avogadro's number

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

Amount of molecules in this case

You can apply the following rule of three, considering the Avogadro's number:  If 1 mole of lithium contains 6.023×10²³ molecules, 2.7 moles of lithium contains how many molecules?

amount of molecules of lithium= (6.023×10²³ molecules × 2.7 moles)÷1 mole

amount of molecules of lithium=1.62621×10²⁴ molecules

Finally, the number of molecules of lithium is 1.62621×10²⁴ molecules.

On the other hand you can apply the following rule of three, considering the Avogadro's number:  If 1 mole of sodium chloride​ contains 6.023×10²³ molecules, 1.8 moles of  sodium chloride​ contains how many molecules?

amount of molecules of sodium chloride= (6.023×10²³ molecules × 1.8 moles)÷1 mole

amount of molecules of sodium chloride=1.08414 ×10²⁴ molecules

Finally, the number of molecules of sodium chloride is 1.08414×10²⁴ molecules.

Part 1. A chemist reacted 15.0 liters of F2 gas with NaCl in the laboratory to form Cl2 and NaF. Use the ideal gas law equation to determine the mass of NaCl that reacted with F2 at 280. K and 1.50 atm.


F2 + 2NaCl → Cl2 + 2NaF


Part 2. Explain how you would determine the mass of sodium chloride that can react with the same volume of fluorine gas at STP.


explain please (for 40 pts)

Answers

Answer:

113 g NaCl

Explanation:

The Ideal Gas Law equation is:

PV = nRT

In this equation,

    > P = pressure (atm)

    > V = volume (L)

    > n = number of moles

    > R = 8.314 (constant)

    > T = temperature (K)

The given values all have to due with the conditions fo F₂. You have been given values for all of the variables but moles F₂. Therefore, to find moles F₂, plug each of the values into the Ideal Gas Law equation and simplify.

(1.50 atm)(15.0 L) = n(8.314)(280. K)

2250 = n(2327.92)

0.967 moles F₂ = n

Using the Ideal Gas Law, we determined that the moles of F₂ is 0.967 moles. Now, to find the mass of NaCl that can react with F₂, you need to (1) convert moles F₂ to moles NaCl (via the mole-to-mole ratio using the reaction coefficients) and then (2) convert moles NaCl to grams NaCl (via molar mass from periodic table). It is important to arrange the ratios/conversions in a way that allows for the cancellation of units (the desired unit should be in the numerator).

1 F₂ + 2 NaCl ---> Cl₂ + 2NaF

Molar Mass (NaCl): 22.99 g/mol + 35.45 g/mol

Molar Mass (NaCl): 58.44 g/mol

0.967 moles F₂        2 moles NaCl             58.44 g

If 19.4 mL of a Ca(OH)₂ solution are needed to neutralize 31.5 mL of 0.1 M HC₂H302 solution, what is the concentration (molarity) of the
Ca(OH)₂ solution?
Select one:
O a. 0.009 M
O b. 1.6 M
OC 0.08 M
O d. 0.1 M

Answers

The concentration (molarity) of the Ca(OH)₂ solution needed to neutralize 31.5 mL of 0.1 M HC₂H302 solution is 0.162M (option D).

How to calculate molarity?

The molarity of a solution can be calculated using the following formula:

CaVa = CbVb

Where;

Ca = concentration of acidCb = concentration of baseVa = volume of acidVb = volume of base

31.5 × 0.1 = 19.4 × Cb

3.15 = 19.4Cb

Cb = 0.162M

Therefore, the concentration (molarity) of the Ca(OH)₂ solution needed to neutralize 31.5 mL of 0.1 M HC₂H302 solution is 0.162M.

Ordinary water boils at 100°C. Can it be made to boil at 95°C or 105°C.​

Answers

It can be done. Normally the boiling point of water is 100°C. It will boil at temperature greater than 100°C more quickly. Water can be boiled at 95°C but for that the atmospheric pressure of the water should be decreased which will decrease the boiling point of water.

Concept :

To boil water at 95°C, decrease the atmospheric pressure.

At 105°C, the water will be boiling quickly than normal at 100°C.

The best way is add alcohol .

The common way is that decrease the atmospheric pressure .

This will work as per Boyles law ,and boiling point can be decreased.

but it has few restrictions

You can't decrease pressure simply at normal conditionsFor decreasing pressure you have to go hill tops .

Hence there is a spare way

Add alcohol

General alcohols like ethanol,butanol can decrease the boiling point of water
