Question

A solution is made by dissolving 10.0 g of LiCl in enough water to make 250 mL of aqueous solution. What is the molarity of the solution? Select one: 1. 0.944 M 2. 40.0 M 3. 170 M 4. 2.50 M 5. 0.0400 M A solution is made by dissolving 10.0 g of LiCl in enough water to make 250 mL of aqueous solution.

Explanation / Answer

Molarity = moles / liters of solution

250 mL = .250 L (1 mL = 1000 L)

molar mass of LiCl = 42.39 g/mol

10.0g / 42.39 g/mol = .236 mol

.236 mol / .250 L = 0.944 M
