Value of Lambdamoo for SrCl2 in water at...

Value of `Lambda_moo` for `SrCl_2` in water at `25^@` from the following data :
`{:("Conc".("mol/lt"),0.25,1),(Lambda_(m)(Omega^(-1)cm^(2)"mol"^(-1)),260,250):}`

A

270

B

260

C

250

D

255

Text Solution

Verified by Experts

The correct Answer is:
A
`^^_(m)=^^_(m)^(infty)-bsqrt(c)`
`260=^^_(m)^(infty)-0.5b` .(1)
`250=^^_(m)^(infty)-b` …(2)
on solving (1) & (2) we get
`^^_(m)^(infty)=270Omega^(-1)cm^(2)mol^(-1)`
