Question

empirical formula of an organic compound having molecular weight 60 is CH2O. What is its molecular formula ?

Answer 1

Molecular weight/ empirical weight =60/30=2
This number is used to multiply to the empirical formula and is called n

(ch2o) n=(ch2o) 2=c2h4o2



Hope it helps you

Answer 2

molar mass of CH2O = 12+2+16=30u
n=molecular weight/ empirical formula
= 60/30
= 2
molecular formula = (CH2O)n
= C2H4O2
