What is the osmotic pressure (Π) of a 0.10 M glucose solution at 27 °C (300 K), given R = 0.0821 L·atm/(mol·K)?
Answer and explanation
Correct answer: D. 2.46 atm
Glucose is a non-electrolyte, so i = 1. Using the van 't Hoff osmotic pressure equation: Π = i M R T = 1 (0.10 mol/L) (0.0821 L·atm/(mol·K)) (300 K) = 2.46 atm.
