Question

is their any difference between molar mass and mole?​

Answer 1

Answer:

In chemistry the substance is usually measured using molecular mass and molar mass. They are very important concepts in chemistry. Expression of molar mass is grams per mole. It can also be expressed as kilogram per mole. Molecular mass is expressed in atomic mass units.

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

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

Explanation:

1. MOLAR MASS

2.MOLECULAR MASS

1. Refer to mass of a mole of a substance

2. Refer to the mass of molecules

1. Also known as molecular weight It determines the mass of single molecule.
2. SI unit is g/mol to use in higher calculation Measured in amu It is defined as the mass of Avogadro number of atom/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 =15.9994g/mol Example : Molecular mass of Ca(OH)
