What will be the osmotic pressure in pascals exerted by a solution prepared by dissolving 1.0 g of polymer of molar mass 150,000 in 500 mL of water at `37^@C` ?

A

30.96 Pa

B

34.36 Pa

C

68.72 Pa

D

48.25 Pa

Text Solution

Verified by Experts

The correct Answer is:
B
No. of moles of polymer =`1/(150,000)``pi=CRT = n/VRT`
`pi=1/(150,000)xx(8.314xx10^3xx310)/0.5=34.36` Pa (R=`8.314xx10^3` Pa L `K^(-1) mol^(-1)`)
