Empirical formula of a compound is CH2O. If its molecular mass is 180, then the molecular formula of the compound is-
A
C6H12O6
B
C5 H10 O5
C
C3 H6 O3
D
C3 H8 O4
Answer
C6H12O6
Explanation
Solution
Empirical formula mass = CH2O
(E.F.) = 12 + 2 + 16 = 30
Molecular formula = E.F.massmol.mass×E.F
= 30180×CH2O
= C6H12O6
