1. The MOLE

2. The Mole
Mole: the amount of a substance that contains as many particles as there are in exactly 12g of carbon-12
A mole is similar to a dozen

3. Avogadro’s Number
Avogadro’s number: the number of particles in exactly one mole of a pure substance
Avogadro’s number = 6.022x1023

5. The Mole 1 mol = 6.022 x 1023 atoms Look it’s a conversion factor!
Convert 2.56 mols of Ca to atoms
Convert 5.63 x 1022 molecules of CuBr2 to mols

7. MOLAR MASS

8. Molar Mass Molar Mass: The mass of one mole of a substance
Unit for molar mass is g/mol
Molar mass is numerically equal to the average atomic mass in amu

9. Molar Mass Molar mass of lithium is 6.941 g/mol or 6.941 g 1 mol
Molar mass is a conversion factor
Convert 2.34 mol of Li to g
Convert 150 g of Pb to mol

10. Molar Mass You can also find the molar mass for a molecular compound.
Convert 54.2 g of silver nitrate to mols.
