Question

AN organic compound contains
92.2% Carbon, 4.8% Hydrogen
and its molecular mass is
26g calculate empirical
formula and molecular
formula.​

Answer 1

Answer:

Let the Empirical formula be CHx.

So,

12/(12+x)×100=92.3⟹x=1

Empirical formula =CH

Empirical formula weight =13

Molecular weight = 2×39=78

MW/EW=78/13 =6

Molecular formula=(Empirical formula)

Thus, the molecular formula of the compound is C6H6.
