    Molarity – Definition, Mole Fraction and Weight Percentage

    Molarity Definition (M)

    The molarity (M) of a solution is the number of moles of solute per liter of solution.

    Difference between Solute, Solvent, and Solution

    A solute is a substance dissolved in a solvent to form a solution. A solvent is a substance that dissolves a solute to form a solution. A solution is a mixture of a solute and a solvent.

    Molality (m) – A Brief Introduction

    The molality (m) of a solution measures the number of moles of solute per kilogram of solvent. It is a dimensionless quantity.

    Molality Definition (m)

    The molality of a solution is the number of moles of solute per kilogram of solvent.

    Difference between Molarity and Molality

    The main difference between molarity and molality is that molarity measures the number of moles of solute per liter of the solution. In contrast, molality measures the number of moles of solute per kilogram of solvent.

    Mole Fraction – Definition

    A mole fraction is the ratio of the number of moles of a given component to the total number of moles in the mixture.

    Weight Percentage – Definition

    A weight percentage is a measurement of the weight of a substance in relation to the total weight of the mixture.

    Easy Way to Define Molarity with Formula

    • The molarity of a solution is the number of moles of solute per liter of solution. The molarity can be calculated using the following formula:
    • Molarity = moles of solute/ liters of solution
    • For example, if a solution contains 0.5 moles of solute in 1 liter of solution, the molarity of the solution is 0.5 moles/liter, or 0.5 M.

    How Is the Correct Formula of Molarity Determined?

    The solute concentration in a solution is expressed in molarity (M). To determine the molarity of a solution, the mass of the solute is divided by the volume of the solution.

    Examples Used to Explain Molarity

    1. A 1 Molar (1 M) concentration means that there is 1 mole of solute per liter of solution.
    2. A concentration of 1 millimolar (1 mM) means that there is 1 millimole of solute per liter of solution.
    3. A concentration of 1 micromolar (1 μM) means that there is 1 micromole of solute per liter of solution.
