Answer:

Difference between Molar mass and Molecular mass

MOLAR MASS MOLECULAR MASS

Refers to mass of a mole of a substance Refers to the mass of molecules

Also known as molecular weight It determines the mass of a single molecule

SI unit is g/mol to use in higher calculations Measured in amu

It is defined as the mass of Avogadro number of atoms/molecules or compounds No particular melting point

Measurement given to compounds, atoms or molecules Determined only in molecules

Less accurate than molecular mass Accurate to use in higher calculations

Example: Mass of 1 mole of oxygen is 15.9994 grams. Therefore, the molar mass = 15.9994 g/mol Example:

Molecular mass of Ca(OH)2 = 74 atomic mass units
