A 100.0 ml aqeuous solution that contains 0.50 g of hemoglobin has an osmotic pressure of 0.00178 atm. What is the molar mass of hemoglobin?

Answer 1

pi = MRT
Substitute and solve for M = molarity
Then M = mols/L. You know M and L, solve for mols

Then mols = grams/molar mass. You know grams and mols, solve for molar mass

Answer 2

68724.16

Answer 3

Can u show the steps on how u got that answer ?
