Review: What is a mole? Parts are formula units, molecules, or atoms 1 mole = 6.02 x 1023 parts Mass is measured in grams. 1 mole = the molar mass of a substance Molar mass is calculated using the atomic mass of the elements in the substance. Every atom in the substance is used to calculate the molar mass.

2. or what the mass of a specific number of particles is. Two step conversions: 1. Used to determine the number of particles in a particular mass of a substance 2. or what the mass of a specific number of particles is.
