Suggest a way to determine the `Lambda_(m)^(@)` value of water.

Explanation

`Lambda_(m)^(@)` of water can be determined by using Kohlrausch law.
`Lambda_(m)^(@)(H_(2)O)=lambda_(H^(+))^(@)+lambda_(OH^(-))^(@)`. If `Lambda_(m)^(@)(HCl), Lambda_(m)^(@)(NaOH)` and `lambda_(m)^(@)(NaCl)` are known, `Lambda_(m)^(@)(H_(2)O)` can be calculated by using the relation,
`Lambda_(m)^(@)(H_(2)O)=Lambda_(m)^(@)(HCl)+Lambda_(m)^(@)(NaOH)-Lambda_(m)^(@)(NaCl)`
