Question

A compound contains 4.07% hydrogen, 24.27% carbon and 71.65% chlorine. It molar mass is 98g. What are its empirical and molecular formulas? (Atomic mass of C=12,H=1,Cl=35)

Solution

Let us assume the mass to be 100g
No. of moles of H=4.071=4.074
No of moles of Cl=71.6535.5=2.012
No. of moles of C=24.2712=2.022
nc:nH:nCl=2:4:2=1:2:1=C:H:Cl
therefore Empirical formula=CH2Cl
But Molecular formula =n× Empirical formula
n=Molar massEmpirical Formula mass
=9812+2+35
=2.1
n2
Molecular formula=2×(CH2Cl)
=C2H4Cl2
