Hydrogen peroxide is oxidized with permanganate solution to produce oxygen gas by the following reaction:

2H + H2O2 + 2MnO4 -> 2MnO2 + 4H2O + 3O2

In the lab a student mixed 30.0 mL of 0.30 M hydrogen peroxide solution with 30.0 mL of 0.30 M potassium permanganate solution. The oxygen that was produced was collected by water displacement at 298 K and 1.00 atm of pressure. The volume of oxygen collected was 178 mL. (Ignore the effect of water vapor in the collection tube here.)

a.) What is the limiting reactant?

b.) What is the theoretical yield of oxygen gas, in milliliters?

c.) What is the percent yield of oxygen gas?
