A gaseous organic compound has an empirical formula $C_xH_y$. When 0.150 g of the compound is completely combusted, it produces 0.225 g of $CO_2$ and 0.090 g of $H_2O$. Given the vapor density of the compound is 29, what is the molecular formula?

An organic compound contains 49.3% carbon, 6.84% hydrogen and its vapour density is 73. Molecular formula of compound is

An organic compound contains 40% carbon, 6.67% hydrogen, and 53.33% oxygen. Its vapour density is 30. What is its molecular formula?

An organic compound having molecular mass 60 is found to contain C=20%, H=6.67% and N=46.67% while rest is oxygen. On heating it gives ${\rm{N}}{{\rm{H}}_3}$ along with a solid residue. The solid residue gives violet colour with alkaline copper sulphate solution. The compound is
