Question

Calculate the value of `Lambda_(m) ^prop` for `SrCl_(2)` in water at `25^(@)C` from the following data `:`
`{:(Conc. (mol//l t),,0.25,,1),(Lambda_(m)(Omega^(-1)cm^(2)mol^(-1)),,260,,250):}`
A. 270
B. 260
C. 250
D. 255

Answer 1

Correct Answer - 1
`Lambda_(m)=Lambda_(m)=-bsqrt(c)`
`260=Lambda_(n)^(oo)-0.5b" "...(1)`
`250=Lambda_(m)^(oo)-b" "...(2)`
On solving `(1) & (2)`, we get
`Lambda_(m)^(oo)=270Omega^(-1)cm^(2)mol^(-1)`
