Number of moles:

n = sample mass / molar mass

n = 15.00 / 74.6

n = 0.2010 moles of KCl

Therefore:

Molarity = moles / Volume

0.1107 = 0.2010 / V

V = 0.2010 / 0.1107

V = 1.815 L

Answer:

1.81 liters of KCl solution

Explanation:

Molarity is expressed as:

[tex]Molarity=\frac{molesofsolute}{litersofsolution}[/tex]

Solving for Liters of solution:

Liters of solution = [tex]\frac{molesofsolute}{Molarity}[/tex] (1)

Using the molecular weight fo the KCl to find the moles of solute:

[tex]15.00gKCl*\frac{1molKCl}{74.6gKCl}=0.20molesKCl[/tex]

Replacing in the formula (1):

Liters of solution = [tex]\frac{0.20molesKCl}{0.1107M}[/tex]

Liters of solution = 1.81 liters
