A compound contains 4.07% hydrogen, 24.27% Carbon and 71.65%, Chlorine. Its molar mass is 98.96. Calculate is Empiricla and Molecular formulae.

Text Solution

Verified by Experts

Empirical formula `=CH_(2)Cl`
Molecular formula `=nxx` Empirical formula
`n=("molar mass")/("Empirical formula mass")=89.96/48.5=2.04=2`
Molecular formula `=2xxCH_(2)Cl=C_(2)H_(4)Cl_(2)`
