Question

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

Answer 1

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

Step-by-step 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 =(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 =(0.5\ moles )/(5.0\ L)`

on calculation,

Molarity = 0.1 mol/L

Molarity = 0.1 M

(M = mol/L)
