Objectives:

1. Students will be able to utilize BCA tables to solve stoichiometry problems. 

2. Students will be able to solve mass to mass stoichiometry problems.

3. Students will be able to calculate a Percent Yield for a chemical reaction via stoichiometry.

Warm-Up: 

Part 1- Classify and balance the reaction below:

____  Sr₃N₂  +  ____  PtNO₂  -->  ____  Sr(NO₂)₂  +  ____  Pt₃N  

Click here for the coefficients for the balanced chemical reaction.

Part 2- Mass to Mass Stoichiometry

How many grams of Sr₃N₂ (290.88 g/mol) would be required to produce 150.0 grams of Pt₃N (599.25 g/mol) 

Assume excess PtNO₂.
