Assume that you know the molar conductances of HCl, NaCl and `CH_(3)COO` Na at infinite dilution. How will you find the molar conductance of `CH_(3)COOH` from them.

Explanation

It can be done by using Kohlrousch a law as explained below:
`lamda_(m)^(0)(CH_(3)COOH)=lamda_(m)^(0)(CH_(3)COO^(-))+lamda_(m)^(0)(H^(+))`
`=lamda_(m)^(0)(CH_(3)COO^(-))+lamda_(m)^(0)(Na^(+))+lamda_(m)^(0)(H^(+))lamda_(m)^(0)(Cl^(-))`
`-lamda_(m)^(0)(H^(+))-lamda_(m)^(0)(Cl^(-))`
`=lamda_(m)^(0)(CH_(3)COONa)+lamda_(m)^(0)(HCl)-lamda_(m)^(0)(HCl)`
knowing the value of `lamda_(m)^(0)(CH_(3)COONa),lamda_(m)^(0)(HCl) and lamda_(m)^(0)(HCl)`, the value of `lamda_(m)^(0)(CH_(3)COOH)` can be calculated.
