Understanding Molarity

Molarity (M) is a unit of concentration that represents the number of moles of solute per liter of solution.

Calculations

1. Convert mL to L:

100 mL = 0.1 L

2. Calculate Molarity:

Molarity (M) = moles of solute / liters of solution

M = 0.2 moles / 0.1 L

M = 2 M

Answer: The molarity of the solution is 2 M.
