    Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
    Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
    Mole is a standard scientific unit for measuring large quantities of very small entities such as atoms and molecules. One mole contains exactly 6.022 ×1023particles (Avogadro's number)

    Identify the compound: write down the chemical formula of the compound. For example, water is H2O, meaning it contains two hydrogen atoms and one oxygen atom.
    Find atomic masses:look up the atomic masses of each element present in the compound. The atomic mass is usually found on the periodic table and is given in atomic mass units (amu).
    Calculate molar mass of each element:multiply the atomic mass of each element by the number of atoms of that element in the compound.
    Add them together:add the results from step 3 to get the total molar mass of the compound.
