Differentiate between molecular mass and molar mass.
Answers
Molecular mass:
Molecular mass of a compound is defined as the mass of one molecule. Molecular mass differs because of the isotopes. The unit in which molecular mass is measured is amu. Amu stands for atomic mass units.
Molar mass:
It is defined as the mass of substance for a given amount. The amount of molecules or atoms or compounds present in one mole of substance is given by this. Molar mass SI unit is g/mol

Molecular mass:

Molar mass:
It is defined as the mass of substance for a given amount. The amount of molecules or atoms or compounds present in one mole of substance is given by this. Molar mass SI unit is g/mol
To make you understand how molar mass and Molecular mass is different from each other, here are the some of the major differences molar mass and molecular mass:
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
