A solution of sucrose (molar mass = 342 ...

A solution of sucrose (molar mass = 342 g/mol) is prepared by dissolving 68.4 g of it per litre of solution, what is its osmotic pressure at 273 K?
`(R = 0.081 L atm K^(-1) mol^(-1))`

A

6.02 atm

B

4.48 atm

C

4.04 atm

D

5.32 atm

Text Solution

Verified by Experts

The correct Answer is:
B
`pi=CRT`
`pi=(w xx R xx T)/(mV)=(68.4xx0.0821xx273)/(342)=4.48` atm
