Question

A compound X contains 20% carbon. 46.67%- N, 26.67% Oxygen, and remaining H. Find its empirical formula and molecular formula if the relative molecular weight of X is 60​

Answer 1

C      H         N    O

20        6.7        46.67          26.63

20/12        6.7     46.67/14 26.63/16

1.6        6.7          3.3         1.6

1        4         2        1

CH4N2O formal mass=60

molecular mass=60

n=60/60=1

Molecular formula CH4N2O
