Question

0.078 of a hydrocarbon occupy 22.4 volume at stp has emperical formula of hydrocarbon is HC what is its molecular formula

Answer 1

22.414 ml of gaseous hydrocarbon at S.T.P has

mass = 0.078g

22414 ml of gaseous hydrocarbon at S.T.P will

have mass =78g

There fore Molar mass of hydrocarbon =78g mol-1

Empirical formula mass of hydrocarbon (CH)

=12+1=1
