Text Solution

Verified by Experts

The correct Answer is:
A
Molecular mass of `C_(2)H_(5)OH= 46.00`
`because [("Atomic mass of C= 12.00"),("Atomic mass of O=16.00"),("Atomic mass of H=1.00")]`
Also, `because` 46.00 of `C_(2)H_(5)OH` contain, C=24g
`therefore 100g` of `C_(2)H_(5)OH` contain, `C= (24 xx 100)/(46)` (52.17%=52%)
