Question

A solution of sucrose (molar mass = 342 g/mol) is prepared by dissolving 68.4 g of it per litre of the solution, what is its osmotic pressure `(R =0.082 "lit. atm." k^(-1)mol^(-1))` at 273 K
A. 6.02 atm
B. 4.48 atm
C. 4.04 atm
D. 5.32 atm

Answer 1

Correct Answer - B
`pi=CRT`
`pi=(w xx R xx T)/(mV)=(68.4xx0.0821xx273)/(342)=4.48` atm
