1. 4 steps Balance equations Get to moles of what you are given
Covert to moles of what you are trying to figure out
Convert to units that you are trying to find

2. Stoich Review
Write a balanced equation showing the formation of ammonia at STP by reacting hydrogen and nitrogen gasses.
N2 + 3 H2 2NH3

3. How many moles of nitrogen are needed to react with 4
How many moles of nitrogen are needed to react with 4.5 moles of hydrogen?
Hint: Use mole ratio
1.5 Moles N2
How many grams of nitrogen would be required to react with 45.4 g of H2?
Hint: Convert to moles, use mole ratio convert to grams
g N2

4. How many liters of ammonia would be produced by the reaction of 34
