Limiting molar conductivity for some ion...

Limiting molar conductivity for some ions is given below (in S `cm^(2) mol^(-1)` ) :
`Na^+ -50.1 , Cl^(-) - 76.3 , H^(+) - 349.6 , CH_3COO^(-) -40.9 , Ca^(2+) -119.0`
What will be the limiting molar conductivities `(Lambda_m^@)` of `CaCl_2, CH_3COONa ` and NaCl respectively ?
