If `0.765 g` of an acid gives `0.535 g` of `CO_(2)` and `0.138 g` of `H_(2)O`, then the ratio of the percentage of `C` to `H` is

A

`19:2`

B

`18:11`

C

`70:17`

D

`1:7`

Text Solution

Verified by Experts

The correct Answer is:
A
% `C=12/44xx(0.535)/(0.765)xx100=2.004.`
% `H=2/18xx(0.138)/(0.765)xx100=2.004`
`therefore` C:H=19:2 approx.
