Hydrocarbons - Lecture 12

A hydrocarbon contains 10.5 g of carbon per gram of hydrogen. 1 L of vapour of the hydrocarbon at 127^(@)C and 1 atm pressure weighs 2.8 g . Find the molecular formula of the hydrocarbon.

If 13 L 4 A 7 = 41 and 14 A 3L 12 = 54 , then 12 L 3 A9 = ?

A hydrogen contains 10.5 g of carbon per gram of hydrogen. If 1 L of the vapour of the hydrocarbon at 127^(@)C at 1 atm pressure weights 2.8 g , then find the molecular formula of the hydrocarbon.

A hydrocarbon contains 10.5 gm carbon and 1 gm hydrogen. Its 2.4 gm has 1 L volume at 1 atm and 127^(@)C , hydrocarbon is
