Calculate the osmotic pressure of `5%` solution of cane sugar (sucrose) at `300 K`.

Text Solution

Verified by Experts

Mw = Molecular mas of sucrose `(C_(12)H_(22)O_(11)) = 342`
`W = 5 g, V=300 mL = 0.3 L`
`R=0.082,T=300 K`
Applying the equation `piV = (W)/(Mw)RT`
`pi=(5)/(342)xx(1)/(0.3)xx0.082xx300`
`= 1.198 atm`
