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 (R=0.082 L atm$K^{- 1}\ mol^{- 1}$) at 273 K?

(b)
Osmotic pressure ($\pi$)=CRT
Here, C = concentration of solution
C=$\frac{n}{V}$
n=$\frac{w}{m} = \frac{weight\ in\ gram\ of\ substance\ }{mol.weight\ ofsubstance\ }$
V=1L
C=$\frac{68.4}{342}$
$\pi$ =$\frac{68.4}{342} 	imes 0.082 	imes 273$
=4.48 atm
