when a certain conductance cell was filled with KCI solution (conductivity = 0.03${\mathrm{\Omega }}^{-1}{\mathrm{cm}}^{-1}$) was it had a resistance of 100$\mathrm{\Omega }$ at 300 K temperature when filled with 0.01 MK₂SO₄, it has a resistance of 300$\mathrm{\Omega }$. Calculate molar conductivity of K₂SO₄ solution in terms of ${\mathrm{\Omega }}^{-1}{\mathrm{m}}^2{\mathrm{mol}}^{-1}$.
