300 mL solution at 27 °C contains 0.2 mol of a nonvolatile solute. Ca

1.	300 mL solution at 27 °C contains 0.2 mol of a nonvolatile solute. Calculate osmotic pressure of the solution.
Answer» Given : V = 300 ml = 0.3 dm³ ; T = 273 + 27 = 300 K π = 0.2 mol, π = ? π = \(\frac{nRT}{V}\) = \(\frac{0.2\times0.08206\times 300}{0.3}\) = 16.41 atm ∴ Osmotic pressure = π = 16.41 atm.

300 mL solution at 27 °C contains 0.2 mol of a nonvolatile solute. Calculate osmotic pressure of the solution.

Answer»

Given :

V = 300 ml = 0.3 dm³ ;

T = 273 + 27 = 300 K

π = 0.2 mol,

π = ?

π = \(\frac{nRT}{V}\)

= \(\frac{0.2\times0.08206\times 300}{0.3}\)

= 16.41 atm

∴ Osmotic pressure = π = 16.41 atm.
