    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.
