1. Chem Take out Packet from yesterday. Today: More Stoichiometry
Stoichiometry is essentially molar conversions but with balanced chemical equations
More Practice with mole-mole calculations
Mole-gram calculations

2. 18 eggs
2 tbsp
6 eggs
= 6 tbsp

3. #s in balanced equation tells you # moles!!
0.400 mol KClO3
3 mol O2
0.6 mol O2
2 mol KClO3

5. 2.46 g H2O
1 mol H2O
8 mol CO2
mol CO2
18.02 g H2O
10 mol H2O
Use molar mass to convert from grams to moles!

6. 95 g Fe
1 mol Fe
3 mol S
32.06 g S
2 mol Fe
1 mol S
55.85 g Fe
= 81.8 g S
