Answer:
The osmotic pressure is 24.6 atm
Explanation:
π = M . R . T . i → Formula for osmotic pressure
i = 2 ⇒ NaCl → Na⁺ + Cl⁻
i means Van't Hoff factor, which indicates the numbers of ions dissolved, by the stoichiometry.
R → Universal gases constant
T→ T° in K → T°C + 273 → 25°C + 273 = 298K
π = Osmotic pressure
Let's replace data given ⇒ π = 0.503 mol/L . 0.082L.atm/mol.K . 298K .2
π = 24.6 atm
