The Mole

2. Measuring Matter
Mole (mol): Base SI unit used to measure the amount of a substance
The Atomic Mass is the amount of 1 mole of substance in grams.
Also known as the Molar Mass
Avogadro's Number: x 1023 is the amount of molecules in one mole.
Molecules = Representative Particles

3. Conversions

Quick Practice Answers Place the following numbers into their common vernacular 2 = 1 Pair 12 = 1 Dozen 6.02 x 1023 Molecules = 1 Mole

5. Using Dimensional Analysis with Moles
Using Avogadro's Number, the number of moles, the molar mass and dimensional analysis, one can move back and forth between different units.
Number of Moles x Number of Grams = Total Mass
1 Mole
Number of Moles x 6.02 x 1023 Particles = Total Particles
Number of Particles x 1 Mole = Total Moles
6.02 x 1023 Particles

6. Using Dimensional Analysis with Moles
Using Avogadro's Number, the number of moles, the molar mass and dimensional analysis, one can move back and forth between different units.
