Understanding Molarity

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

Formula

Molarity (M) = Moles of solute / Liters of solution

Calculations

1. Convert mL to L: 200 mL = 0.2 L

2. Plug in the values:

M = 0.2 moles / 0.2 L

3. Calculate: M = 1 M

Answer: The molarity of the solution is 1 M.
