A gaseous hydrocarbon contains 82.76% of carbon. Given that it's vapours density is 29, find it's molecular formula. [C = 12, H = 1]

Element | % composition | At. wt. |Relative no. of atoms| Simplest ratio --------|---------------|---------|----------------------|---- Carbon |82.76 | 12 | = 6.89 | = 1 Hydrogen | 17.24 | 1 | = 17.24 | = 2.5 Simplest ratio of whole numbers = C : H = 1 : 2.5 = 2 : 5 Hence, empirical formula is C 2 H 5 Empirical formula weight = 2(12) + 5(1) = 29 V.D. = 29 Molecular weight = 2 x V.D. = 2 x 29 Molecular formula = n[E.F.] = 2[C 2 H 5 ] = C 4 H 10
