1. Molar Conversions

2. Mass of 1 mole is different for every substance
1mole = x 1023 particles
Particles = molecules, formula units, atoms
Mass of 1 mole is different for every substance
For elements mass of 1 mole = average atomic mass on the Periodic Table
We can use these # as conversion factors to change from 1 unit to another.
