Question

Phenylalanyl aspartate, Nutrasweet, is an artificial sweetener used in many diet drinks. If a solution prepared by dissolving 6.068 mg of Nutrasweet in 125 milliliters of water exhibited an osmotic pressure at 25ÂșC of 3.23 mm Hg, what is the molar mass of Nutrasweet?

Answers

pi = MRT
Substitute pi(in atmospheres) into the osmotic pressure equation and solve for n = number of moles. Then
n = grams/molar mass.
You know n and grams, solve for molar mass.
Thank you very much!
