Chemistry A compound contains 92.3% CARBON and 7.7% HYDROGEN. The molecule of the compound is 39 times heavier than hydrogen molecule. The molecular formula of the compound is:
Medium Answer Open in answr app Correct option is D C 6
H 6
Let the Empirical formula be CH x
. So, 12+x 12
×100=92.3⟹x=1 Empirical formula =CH Empirical formula weight =13 Molecular weight = 2×39=78 EW MW
= 13 78
=6 Molecular formula=(Empirical formula) 6
Thus, the molecular formula of the compound is C 6
H 6
