Question

The molar conductivity of a `0.5 mol//dm^(3)` solution of `AgNO_(3)` with electrolytic conductivity of `5.76 xx 10^(-3) S cm^(-1)` at `298 K` is
A. 2.88 S `cm^(2)//mol`
B. `11.52S" "cm^(-2)//mol`
C. `0.086S" "cm^(2)//mol`
D. `28.8S " "cm^(2)//mol`

Answer 1

Correct Answer - B
`M=0.5M`
`wedge_(m)=Kxx(1000)/(M)`
`5.76xx10^(-3)xx(1000)/(0.5)`
`=11.52S" "cm^(2)//mol`
