Question

An organic compound x contains 40% carbon, 6.67% hydrogen, the rest being oxygen. if x has a relative molecular mass of 60 determine it

1 .empirical formula
2. molecular formula​

Answer 1

emprical weight=ch2o

=12*12*1*1*16 =30

Molecular mass=n*emprical weight

60=n*30

N=60/30=2

Molecular formula=n*emprical formula=2*30

=60

C2h4o2

Hope this helps :)
