Q.6 Empirical formula of compound is C1H201 and relative decnsity
is 30 what will be molecular formula?
A. C1H201
B. C2H4O2
c C3H603
D. C4H804​

Answer 1

Answer:

B. C2H4O2

Explanation:

Molecular mass = 2 x  Density

= 2 x 30 = 60

Mass of carbon = 12

Mass of Hydrogen = 2 x 1 = 2

Mass of Oxygen = 16

Total mass = 12 + 2 + 16 = 30

So, to have molecular mass as 60, we must multiply the compound by 2.

After multiplying, we get

C2H4O2

This the molecular formula for the compound
