Answer:

Molarity

Explanation:

We need to know the definition of molarity;

What is molarity?

  • Molarity is the concentration of a solution in moles per liter.

How is molarity calculated?

  • Molarity is calculated by dividing the amount of solute in moles by the volume of solution in liters.

Example;

  • If a 0.25 moles of Sodium hydroxide are dissolved in 500 mL of solution. Then molarity will be;

Molarity = Moles ÷ Volume

              = 0.25 moles ÷ 0.5 L

              = 0.5 Mol/L

Therefore, the molarity of sodium hydroxide solution will be 0.5 mol/L.
