Molarity Calculator

The molarity of a solution is the number of moles of solute per liter of solution. Molarity allows for easy dilution of a solution using the dilution formula where the initial concentration multiplied by the initial volume is equal to the final concentration multiplied by the final volume (M1V1=M2V2). Multiplying the molarity by the volume gives the total moles of the material, which can be diluted to any lower concentration.

    Formula

    Molarity= [(% x d) / MW] x 10

    Where,
    %=Weight Percentage,
    d=Density,
    MW=Molecular Weight.

    Molarity refers to:
    1) Number of moles of solute per litre of solution.
    2) the number of moles of a solute dissolved in a liter of solvent. Note: be careful not to confuse molarity and molarity. Molarity is represented by a small "m," whereas molarity is represented by an upper case "M."
    3) The number of moles of solute in q liter of solution.

    Example:
    Calculate the Molarity for the given details.
    Weight percentage = 250
    Density = 50
    Molecular weight/Formula Weight = 25

    Solution:
    Apply Formula:
    Molarity= [(% x d) / MW] x 10

    Molarity = 5000
