What is the osmotic pressure of a 0.850 m solution of glucose in water at 35 °c?
Alik [6]

The osmotic pressure of the glucose solution is 21.49 atm.

From the question given above, the following data were obtained:

  • Molarity (M) = 0.85 M
  • Temperature (T) = 35 °C = 35 + 273 = 308 K
  • Van't Hoff's factor (i) = 1 (non-electrolyte)
  • Gas constant (R) = 0.0821 atm.L/Kmol
  • Osmotic pressure (π) =?

π = iMRT

π = 1 × 0.85 × 0.0821 × 308

π = 21.49 atm

Therefore, the osmotic pressure is 21.49 atm
