  1. Mass-Volume Stoichiometry Problems

  2. In a mass-volume (or volume – mass) problem, you will be given either the mass or volume of one substance and asked to calculate the mass or volume of another substance.

  3. STOICHIOMETRY MASS A VOLUME A MASS B VOLUME B MOL “A” MOL “B”

  4. Example 1 Calculate the volume (in liters) of oxygen gas required to react with 50 g of aluminum at STP. 4Al(s) + 3O2(g)  2Al2O3(s)

  5. Example 2 An automobile airbag inflates when N2 gas results from the explosive decomposition if sodium azide (NaN3). 2NaN3(s)  2Na(s) + 3N2(g)

  6. a. Calculate the mass of NaN3 required to produce 50L of N2 gas at STP.

  7. b. What volume (in L) of N2 gas is produced when 175g of sodium is formed at STP?
