The mass of acetic acid present in `500 ml` of solution in which it is `1%` ionides (Ka of ` CH_(3)COOH = 1.8 xx 10^(-4)`)

A

`5.4`

B

`12.6`

C

`6.4`

D

`10.8`

Text Solution

Verified by Experts

The correct Answer is:
A
Normality `=(Ka)/(alpha^(2))=(1.8xx0^(-5))/((10^(-2))^(2))=1.8xx10^(-1)N`
`W=(1.8xx10^(-1)xx60xx500)/(1000)=5.4g`
