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.

Any substance requires a constant number of molecules to make one mole; however, the molar masses of different molecules vary because of their different atomic 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.

Mole is a unit used in chemistry to represent the amount of a substance, while molar mass is the mass of one mole of that substance. Mole is expressed in mol, while molar mass is expressed in grams per mole (g/mol).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
