Question

What’s the molarity of a solution created by dissolving 0.60 moles of KCL in 2.0 L of water

Answer 1

Answer:

Molarity = 0.3 M

Explanation:

Given data:

Number of moles of KCl = 0.60 mol

Volume of water = 2.0 L

Molarity  = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

Molarity = 0.60 mol / 2.0 L

Molarity = 0.3 mol/L

Molarity = 0.3 M
