`overset(@)wedge` for NaCI HCI and NaAC are 126.4 425.9 , and 91.0 S `cm^(2) "mol"^(-1)` respectively calulate `overset(infty)wedge m` for Hac.

A

390.5

B

29.5

C

208.5

D

217.4

Text Solution

Verified by Experts

The correct Answer is:
D
`Lambda(HOAc) = Lambda^(@)(NaOAc) + lambda^(@) (HCl) - Lambda^(@) (NaCl)`
`= 91 + 425.9 - 126.4 = 390.5`
