Chapter 19, Problem 89P(choose chapter or problem)
A solution is made by dissolving 23.88 mg of a protein in water and diluting to a total volume of 20.0 mL. The osmotic pressure of the solution is 3.66 torr at \(25^\circ \mathrm C\). What is the molar mass of the protein? (The osmotic pressure of a solution is given by the following equation: Osmotic Pressure = \(\mathrm{M \times R \times T}\), where M is the molarity of the solution, R is the gas constant, and T is temperature in K.)

QUESTION:
A solution is made by dissolving 23.88 mg of a protein in water and diluting to a total volume of 20.0 mL. The osmotic pressure of the solution is 3.66 torr at \(25^\circ \mathrm C\). What is the molar mass of the protein? (The osmotic pressure of a solution is given by the following equation: Osmotic Pressure = \(\mathrm{M \times R \times T}\), where M is the molarity of the solution, R is the gas constant, and T is temperature in K.)
ANSWER:Step 1 of 2
Given:
Mass of protein = 23.88 mg = 0.02388 g
Volume = 20.0 mL = 0.020L
Temperature = 25 °C + 273 = 298K
Osmotic pressure = 3.66 torr
