A solution contains 0.02755 g of a protein in 25.0 mL of solution. The osmotic pressure is 3.22 torr at 298 K. What is the molecular weight of the protein?
Answered by DrBob222
pi = ZMRT.
pi should be in atm (3.22/760).
T must be in kelvin. Solve for M in mols/L. Then moles = grams/molecular weight.. You know grams and mols, solve for molecular weight.

How do I find mols?
