84.0 mol H2O. The reaction of 84.0 mol of O2 produces 84.0 mol of CO2.
(a) Write the partially balanced equation in terms of O.
We assume that all the CO2 comes from the O in O2.
O2 + … → CO2
(b) Use the molar ratio of CO2:O2 to calculate the moles of CO2.
Moles of CO2 = 84.0 mol O2 x (1 mol CO2/1 mol O2) = 84.0 mol CO2
