    Molarity is the concentration of a solution expressed as the number of moles of solute per litre of solution.

    Explanation:

    To get the molarity, you divide the moles of solute by the litres of solution.

    Molarity = moles of solutelitres of solution

    For example, a 0.25 mol/L NaOH solution contains 0.25 mol of sodium hydroxide in every litre of solution.

    To calculate the molarity of a solution, you need to know the number of moles of solute and the total volume of the solution.

    To calculate molarity:

    Calculate the number of moles of solute present. Calculate the number of litres of solution present. Divide the number of moles of solute by the number of litres of solution.
