Answer:
Osmotic pressure is 1.61 atm
Explanation:
To solve this problem, it is necessary to apply colligative property of osmoitc pressure. The formula is: π = M . R . T
We determine the data:
M = Molarity (mol/L) → 0.2 mol/3L = 0.066M
R = 0.082 L.atm/mol.K → Universal constant gases
T = Absolute T° → T°C + 273 = 298K
We replace data: 0.066 M . 0.082 L.atm/mol.K . 298 K = π
1.61 atm = π
