Question

An organic compound contains 40.65% carbon 8.55% hydrogen and 23.77%nitrogen . its vapour density in 29.5. find its molecular formula

Answer 1

vapour density =29.5. , molecular mass = 2× vapour density i.e 59.
now carbon ratio of atoms =40.65/12
now hydrogen ratio of atoms =8.55/1
nitrogen. =22.77/14
ratio of atoms found
now just make the molecular formula in whole number ratio
