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 $K^{- 1} m o l^{- 1}$ ) at 273 K?

Options:

Answer:

Solution:

Sucrose is non ionisable so i = 1
$π = i CRT$
$= 1 \times \frac{\frac{68.4}{342}}{1} (0.082) \times 273$
$= 4.477 atm$
$≃ 4.48 atm$
