Alkanes are hydrocarbons that belong to a homologous series with the general formula CnH2n+2C_nH_{2n+2}CnH2n+2.
An alkane molecule is known to contain 34 hydrogen atoms.
Calculate the number of carbon atoms in this molecule, and write down its complete molecular formula.
Practise AQA GCSE Chemistry Carbon compounds as fuels and feedstock with exam-style questions for Foundation and Higher tier. 13 questions covering Crude oil, hydrocarbons and alkanes, Fractional distillation and petrochemicals, Properties of hydrocarbons, and Cracking and alkenes, matched to the AQA GCSE Chemistry (8462) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
