Solutions Question 272
Question: The relationship between osmotic pressure at $ 273,K $ when $ 10g $ glucose $ (P_1),,10g $ urea $ (P_2) $ and $ 10g $ sucrose $ (P_3) $ are dissolved in $ 250ml $ of water is [CBSE PMT 1996]
Options:
A) $ P_1>P_2>P_3 $
B) $ P_3>P_1>P_2 $
C) $ P_2>P_1>P_3 $
D) $ P_2>P_3>P_1 $
Show Answer
Answer:
Correct Answer: C
Solution:
$ P=\frac{w}{mv},R.T $ since wvT are constant thus $ P\propto \frac{1}{m} $
$ P_2>P_1>P_3 $ .
