Mole Theory and Molar Mass

What is a mole? It is simply a quantity that chemists use to measure amounts.

Mole Theory
When talking about the mole (abbreviated as mol) in the field of chemistry, we are simply discussing a unit of measure that represents a large number. That large number, which is called Avogadro's number, is 6.022×1023 mol−1.

How big is Avogadro's number? 602,200,000,000,000,000,000,000 That's almost a billion billions!!
