Answer 1

Since 448 ml of the hydrocarbon weighs.68 gram at STP then the weight of the hydrocarbon is 84 grams. Now since 86% of carbon is in the hydrocarbon , then the hydrocarbon will contain about 14% of oxygen .Now on simplification the empirical formula of the hydrocarbon comes to be CH2 .Thus we get that the compound is C6H12
