Question

In the estimation of carbon and hydrogen, 0.25 g of a compound gave 0.66 g of CO₂ and 0.135 g of H₂O. What is the empirical formula?

Choose one · Correct answer highlighted

CH₂ C₂H₅ CH₃ CH Correct

Mass of C = (12/44) × 0.66 = 0.18 g. Mass of H = (2/18) × 0.135 = 0.015 g. Ratio C:H = (0.18/12)/(0.015/1) = 1:1. Empirical formula = CH.
