A) \[50\]
B) \[180\]
C) \[102\]
D) \[25\]
Correct Answer: C
Solution :
According to Raoult's law \[\frac{P-{{P}_{s}}}{P}=\frac{n}{n+N}=\frac{0.05}{2.5+0.05}\] \[=\frac{0.05}{2.55}=\frac{1}{51}\] Weight of solute \[=\frac{w}{W}\times M\times \frac{P}{P-{{P}_{s}}}\] \[=\frac{10\times 18}{90}\times 51=102\,g\]You need to login to perform this action.
