A water solution of hemoglobin at 310 K has a concentration of 1.00×10^{- 3} M. What is the osmotic pressure of the solution?

Question

Quizplus · Accepted Answer

The osmotic pressure (π) can be calculated using the formula π = iMRT, where i is the van't Hoff factor (1 for hemoglobin, a non-electrolyte), M is the molarity (1.00×10^-3 M), R is the ideal gas constant (0.0821 L·atm/mol·K), and T is the temperature in Kelvin (310 K). Plugging in these values gives π = (1)(1.00×10^-3)(0.0821)(310) = 2.54×10^-2 atm.
