What is the molarity of a 5.0 L solution that contains 0.5 moles of KNO3

pashok25 [27]

Answer:

Molarity of a 5.0 L solution that contains 0.5 moles of KNO3 is 0.1 M

Explanation:

Molarity : It is used to express the concentration of the solution and defined as total moles of solute present in one liter of solution .

$Molarity =\frac{moles\ of\ solute}{volume\ of\ solution(L)}$

Moles of KNO3 = 0.5 (given)

Volume of solution = 5.0 L

Substitute the value in given formula ,

$Molarity =\frac{0.5\ moles }{5.0\ L}$

on calculation,

Molarity = 0.1 mol/L

Molarity = 0.1 M

(M = mol/L)
