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

3.92 atm

B

4.48 atm

C

5.92 atm

D

29.4 atm

Text Solution

Verified by Experts

The correct Answer is:
b
Osmotic pressure `(pi)` = CRT
Here, C = concentration of solution
`C = (n)/(V) = (68.4)/(34.2)`
`pi = (68.4)/(342)xx0.082xx273 = 4.48 atm`
