A pure saturated hydrocarbon (C,H2n + 2) is burned with excess air. The orsat analysis of the products of combustion will be 9.08 % CO2, 1.63 % CO, 5.28 % O2 and the rest is nitrogen but no free H2. Compute for the following: a. Formula of the Hydrocarbon b. % Excess Air 4. If the actual yield of C2H6 is 50 g and the theoretical yield of C2H6 is 100 g, what is the % yield? (20 Pts.)
