Step-by-step explanation:

Given,

It contains 4.07 %  H  and 24.27 %  C  

Moles of H = Weight/Atomic wt.of H

                 = 4.07/1

                = ~4.

Moles of C = Weight/Atomic wt. of C

                  = 24.27/12

                 = ~2

Moles of Cl = Weight/Atomic wt. of Cl

                   = 71.65/35.5

                   = ~2

On dividing the ratios by the least value we get,

(4/2) : (2/2) :( 2/2)

= 2 : 1 : 1

Therefore,

The empirical formula is : CH₂Cl.

(ii)

The empirical formula mass of  CH₂Cl = 49.48 u

The molecular mass = 98.96 u

The molecular mass must be an integral multiple of the empirical formula mass.

= 98.96/49.48

= 2

It means,

The molecular formula must be twice the empirical formula.

Therefore,

Molecular Formula = C₂H₄Cl₂

Hope it helps!
