The resistace of a conductivity cell containing 0.001 M KCl solution at 298K is `1500Omega` what is the cell constant if conductivity of 0.001M KCl solution at 298 K is `0.146xx10^(-3)S" "cm^(-1)`

Answer

0.219 `cm^(-1)`

Explanation

Cell constant, `(l)/(a)`
`=k xx R = 0.146 xx 10^(-3) "ohm"^(-1)cm^(-1) xx 1500` ohm
`=0.219cm^(-1)`
