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.

Warm-Up: 

Part 1- Use dimensional analysis to convert the following:

A.  85.0 g  Sr₃P₂ grams  = ? Sr₃P₂ moles                                                        (molar mass = 324.81 g/mol ) 

B.  3.33 moles HBr  = ? HBr grams 

         (molar mass = 80.91 g/mol)

Part 2- Mass to Mass Stoichiometry

                  2  NaHCO₃  -->  1  Na₂CO₃  +  1  CO₂  +  1  H₂O

How many grams of NaHCO₃ (84.01 g/mol) would be required to produce 30.0 grams of water? (18.02 g/mol)
