Write expressions for equivalent conductivity and molar conductivity of `Al_(2)(SO_(4))_(3)` at infinite dilutio in terms of their ionic conductivitiies.

Explanation

`wedge_(eq)(Al_(2)SO_(4))=lamda_(Al^(3+))^(@)+lamda_(SO_(4)^(2-))^(@),wedge_(m)(Al_(2)SO_(4))_(3))=2lamda_(Al^(3+))^(@)+3lamda_(SO_(4)^(2-))^(@)`
