The molar conductivity of a 1-5 M solution of an electrolyte is found to be `138.9 S cm^(2) mol^(-1)` . Calculate the conductivity of this solution.

Text Solution

Verified by Experts

Molar conductivity, `wedge_(m)=138.9"S cm"^(2)"mol"^(-1)`
Molarity = 1.5 M: Conductivity k = ?
Molar conductivitry, `wedge_(m)=(k xx 1000)/("Molarity")`
`or k=(wedge_(m) xx "Molarity")/(1000) = (138.9"S cm"^(2)"mol"^(-1) xx 1.5"mol L"^(-1))/(100cm^(3)L^(-1))`
`=0.208"S cm"^(-1)`
