Calculate the overset(@)Lambda(m) for Mg...

Calculate the `overset(@)Lambda_(m)` for `MgCl_(2)`. The limiting molar conductivities of `Mg^(2+)` and `Cl^(-1)` ions are 106.0 S `cm^(2)" mol"^(-1)` and 76.3 S `cm^(2)"mol"^(-1)`respectively.

Text Solution

Verified by Experts

`overset(@)Lambda_(m)(MgCl_(2))=lambda^(@)mg2+2lambda^(@)Cl^(-)`
`=(106.0S cm^(2)+2xx76.3S cm^(2))`
`overset(@)Lambda_(m)(MgCl_(2))=258.6 S cm^(2)`
