Question

the empirical formula of a compound is CH2O .If ths V.D is 60. Its molecular formula is?

Answer 1

Answer:

molecular formula=2×CH2O=C2H4O2.

Explanation:

MW=2×V.D.=2×30=60g.

Empirical formula weight (E.F.W) =CH

O=12+2+16=30 g.

n=

Answer 2

Answer:

C2H4O2

Explanation:

Empirical formula mass = 30

n× 30 = 60

n = 60/30

= 2

Molecular formula = (CH2O)2

= C2H4O2
