A compound containing only carbon, hydrogen, and oxygen has a molar mass of approximately 90 g/mol. Combustion analysis of 0.405 g of the compound produces 0.54 g $CO_2$ and 0.27 g $H_2O$. If the compound's empirical formula is the same as its molecular formula, what is the number of oxygen atoms in one molecule of the compound?

A compound containing only carbon and hydrogen has an empirical formula of CH2. If its molar mass is approximately 56 g/mol, 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
