A solution is prepared by dissolving 35g hoemoglobin in water to make 1 litter. If osmotic pressure of solution is 10.00mmHg at 25 degree centigrade. Calculate the molarmass of the hoem6globin
Note the correct spelling of liter.
pi = MRT
pi = 10/760 = ?
R = 0.08206
T = 298
Solve for M.
Then M = mols/L. Solve for mols.
mol = g/molar mass. You have grams and mols, solve for molar mass.
