The resistance of 1 N solution of acetic acid is 250 ohm, when measured in a cell of cell constant 1.15 `cm^(-1)` . The equivalent conductance (in `ohm^(-1)` `cm^(2)` `equiv^(-1)` ) of 1 N acetic acid is

Options

A. 4.6
B. 9.2
C. 18.4
D. 0.023

Answer

A

Explanation

Applying, `k1/Rxxcell constant =1/250xx1.15`
We know `Lambda_(eq)=kxx1000/"Normality"`
`=1/250xx1.15xx1000/1=4.6ohm^(-1)cm^2eq^(-1)`
