If a 32 g bar of chocolate was completely combusted (to CO2 and H2O) with a stoichiometric equivalence of oxygen, how many grams of oxygen would be required? Assumptions (may or may not be needed): Chocolate has the average formula between a triacylgrycerol (fat) and dextrose (a sugar) of C45H66O9 (MW=751 g/mol) Air = 21% oxygen, R= 0.082 L.atm.K-1.mol-1, 1 gallon = 3.785 L, T=278 K, P = 1 atm Round your answer to the nearest 0.1 grams and do not include units in the answer.
