pi = MRT
Substitute and solve for molarity, M.
Then M = moles/L
You know M and L, solve for moles, then
moles = g/molar mass. Solve for molar mass.
The osmotic pressure of a solution containing 5.00 mg of an unknown protein per 10
mL of solution was 2.73 torr at 25 °C. Find the molar mass of the unknown protein.
