Question

determine the empirical formula of an organic hydrocarbon compound which contains 80 percentage by mass of carbon and 20 percentage by mass of hydrogen if the Mr of the compound is 30 what is the molecular formula.

Ar of C=12
Ar of H=1

80/12=6.7 moles
20/1=20 moles
wut should I do next ?

pls post relevant answers for this question.​
