Answer:
E = 1.602v
Explanation:
Use the Nernst Equation => E(non-std) = E⁰(std) – (0.0592/n)logQc …
Zn⁰(s) => Zn⁺²(aq) + 2 eˉ
2Ag⁺(aq) + 2eˉ=> 2Ag⁰(s)
_____________________________
Zn⁰(s) + 2Ag⁺(aq) => Zn⁺²(aq) + 2Ag(s)
Given E⁰ = 1.562v
Qc = [Zn⁺²(aq)]/[Ag⁺]² = (1 x 10ˉ³)/(0.150)² = 0.044
E = E⁰ -(0.0592/n)logQc = 1.562v – (0.0592/2)log(0.044) = 1.602v

Answer : The molar mass of the solute will be
87.90 g/mol.Explanation : We know the formula for elevation in boiling point, which is
Δt = i
![K_{b}](https://tex.z-dn.net/?f=%20K_%7Bb%7D%20)
m
given that, Δt = 0.357,
![K_{b}](https://tex.z-dn.net/?f=%20K_%7Bb%7D%20)
= 5.02 and mass of
![CCl _{4}](https://tex.z-dn.net/?f=CCl%20_%7B4%7D%20)
= 40,
on substituting the value we get,
0.357 = (1) X (5.02) X (x/ 0.044), on solving we get x = 2.844 X
![10^{-3}](https://tex.z-dn.net/?f=%2010%5E%7B-3%7D%20)
.
Now, 0.250/ 2.844 X
![10^{-3}](https://tex.z-dn.net/?f=%2010%5E%7B-3%7D%20)
=
87.90 g/mol. which is the weight of unknown component.
