Avogadro did not find or create Avogadro's number—it was just named after him out of respect for his work. The Socratica chemistry playlist presents a must-see video introduction to the mole. It details how to convert to moles from mass, volume, and particles. The resource also uses guided practice problems to demonstrate proper conversions.
