Question

What is the difference between mole and molar mass?

Answer 1

A mole is `6.02*10^23` (avogadro's number) molecules of a substance. The molar mass is the amount of mass that 1 mole of that substance possesses.

Explanation:

The amount of molecules of any substance to make 1 mole is constant.
However, due to differing atomic masses, different molecules will have different molar masses.

If you have `6.02*10^23` feathers and `6.02*10^23` bricks, you have 1 mole of each, but the bricks have a lot more mass.
