How to switch between moles, particles and pressure

Teach students the complexities of the mole with mole island!

1. Warm Up 3/10 – Draw this picture:

2. Mole Conversions using Mole Islands MOLE ISLAND (Mole) MASS ISLAND (Grams) Representative ISLAND (atoms, molecules, etc ) Molar Mass Avogadro’s # g/1 mol 6.02x10 23 /1 mol

3. How many moles are in 25 grams of water? 25 g H 2 O G  Mol Find Molar Mass! H 2 O = 18 g/ mol 18 g H 2 O 1 mol H 2 O = 1.4 mol H 2 O

4. How many moles are in 3.4 x 10 23 molecules of H 2 SO 4 ? 3.4 x 10 23 molecules 6.02 x 10 23 molecules 1 mol = 0.56 mol H 2 SO 4

5. How many grams are in 8.2 x 10 22 molecules of N 2 I 6 8.2 x 10 22 molecules Mol  Grams Find Molar Mass! N 2 I 6 = 790 g/ mol 6.02 x 10 23 molecules 1 mol = 107.6 g N 2 I 6 1 mol N 2 I 6 I – 127 N – 14 790 g N 2 I 6
