If the mass of `10^22` molecules of a hydrocarbon is about 1.2 g, then the gram molecular mass of hydrocarbon is :

The gram molecular mass of CO_(2) is

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

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

A gaseous hydrocarbon when burns in oxygen gives 3.38g CO_(2) , 0.690g water and no other product.At STP,volume of 10L of this hydrocarbon is found to weigh 11.6g .What will be the molecular mass of the hydrocarbon.

The number of carbon atoms in a hydrocarbon molecule is 2. Write down the name and molecular formula of the hydrocarbon if it is an: i) alkane
