Molar conductivity $$\\displaystyle \\Lambda$$ and specific conductivity $$\\displaystyle \\kappa$$ are related by the expression as follows:$$\\displaystyle \\Lambda = \\dfrac {1000 \\kappa}{C}$$where $$C$$ is the molar concentration.$$\\displaystyle \\Lambda = \\dfrac {1000 \ imes 0.0248}{0.20} = 124.0 \\: S\\ cm^2 /mol$$
