Problem 90P

A solution is made by dissolving 28.65 mg of a protein in water and diluting to a total volume of 25.0 mL. The osmotic pressure of the solution is 4.55 torr at 25°C. What is the molar mass of the protein? (The osmotic pressure of a solution is given by the equation: Osmotic Pressure = M × R × T, where M is the molarity of the solution, R is the gas constant, and T is temperature in K.)

Step-by-Step Solution:
Step 1 of 3

Here we have to calculate the molar mass of protein.

Given:

Step-1

The given mass of protein (w)= 28.65 mg = 0.02865g

Volume(v) = 25.0 mL = 0.025L

Osmotic pressure(p) = 4.55torr =  4.55/760 = 0.00598  atm

Temperature (T)= 25oC =  298 k (25+273)

Osmotic pressure = M R T

Where, M = molarity, R = gas constant, T = temperature  in K

Step-2

Osmotic pressure = M R T

0.00598 atm = M 0.0821 L atm mol-1 K-1 298...

Step 2 of 3
