A hydrocarbon contains `80%` of carbon by weight.The molecular formula of the hydrocarbon is

2g of a non-volatile hydrocarbon solute dissolved in 100g of a hypothetical organic solvent (molar mass =50 ) was found to lower the vapour pressure from 75.00 to 74.50 mm of Hg at 20^(@)C . Given that the hydrocarbon contains 96% of C , what is the molecular formula of the hydrocarbon ?

A saturated hydrocarbon contains 82.66% carbon. Its molecular formula is

A gaseous hydrocarbon has 85% carbon and vapour density of 28. The possible formula of the hydrocarbon will be

1 litre of a hydrocarbon weight as much as one litre of CO_(2) . The moleecular formula of hydrocarbon is :-
