What is the osmotic pressure (in atmospheres) of a solution prepared by adding 0.200 moles of glucose (C6H12O6) to enough water to make 3.00 L of solution at 25 °C?

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
