Solutions Question 103
Question: A solution contains non-volatile solute of molecular mass $ M_{p} $ . Which of the following can be used to calculate molecular mass of the solute in terms of osmotic pressure (m = Mass of solute, V = Volume of solution and p = Osmotic pressure) [CBSE PMT 2002]
Options:
A) $ Mp=( \frac{m}{\pi } ),VRT $
$ $
B) $ Mp=( \frac{m}{V} )\frac{RT}{\pi } $
C) $ Mp=( \frac{m}{V} )\frac{\pi }{RT} $
D) $ Mp=( \frac{m}{V} ),\pi RT $
Show Answer
Answer:
Correct Answer: B
Solution:
$ \pi =\frac{n}{V}RT $
$ \Rightarrow M_{P}=( \frac{m}{V} )\frac{RT}{\pi } $
