Neco Model Questions Vol1 2023 Chemistry Question 8
Practice objective / multiple choice question 8 from the 2023 Neco Model Questions Vol1 Chemistry examination.
A 10.0 g mixture of two hydrocarbons is completely combusted in excess oxygen. The mixture contains an alkane of formula \( \mathrm{C_nH_{2n+2}} \) and an alkene of formula \( \mathrm{C_mH_{2m}} \) in a mass ratio of 3:2 (alkane : alkene). The combustion produces 30.6 g of \( \mathrm{CO_2} \) and 15.0 g of \( \mathrm{H_2O} \). Determine the molecular formulas of the alkane and the alkene.
