Human blood has a molar concentration of solutes of 0.30 M. What is the osmotic pressure of blood at 25°C? (R = 0.08206 L • atm/K • mol)

Question

Quizplus · Accepted Answer

The osmotic pressure (π) can be calculated using the formula π = iMRT, where i is the van't Hoff factor (assumed to be 1 for blood), M is the molarity (0.30 M), R is the ideal gas constant (0.08206 L • atm/K • mol), and T is the temperature in Kelvin (25°C = 298 K). Substituting these values gives π = (1)(0.30)(0.08206)(298) ≈ 7.3 atm.
