Question

What is the difference between mole and molar mass?

Answer 1

Hint: Chemists needed a simple method for calculating how many molecules are present in a beaker. The mole principle bridges this distance by comparing the mass of a single atom or molecule in the atomic mass unit to the mass of a vast collection of such molecules in gram.

Complete answer:
The mole is a unit of measurement equivalent to the pair, dozen, gross, and so on. It gives a precise count of the number of atoms or molecules in a bulk sample of matter. A mole is the mass of a material containing $6.023 \times {10^{23}}$ particles of that substance. The mole is the SI unit for measuring the quantity of a material. It is represented by the symbol mol. It is also known as the volume of material that contains the same number of discrete entities.
The mass in grams of one mole of a material is known as its molar mass. Molar mass is expressed in grams per mole. A chemical compound's molar mass is defined as the mass of a sample of that compound divided by the volume of material in that sample, expressed in moles.
The difference between mole and molar mass is that the number of molecules used to produce one mole of any substance is constant. Different molecules, however, would have different molar masses due to their different atomic masses.

Note:
It must be noted that since most quantitative chemical equations are based on the mole concept, understanding of what a mole is, is essential for the study of chemistry. Understanding of how the mole relates to mass and the number of individuals is crucial.
