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

`20:17`

D

`1:7`

Text Solution

Verified by Experts

The correct Answer is:
A
`%` of `C=(12)/(44)xx(0.535)/(0.765)xx100=18.07`
`%` of `H=(1)/(18)xx(0.138)/(0.765)xx100=2.004`
Ratio of `%` of `C , H = 19 :2` (approx)
