A nonelectrolyte, aqueous solution contains 3% phenylalanine (C9H11NO2) (Molar mass = 165.21 g/mol) by mass at 25.0 oC. The density of the solution is 1.00 g/ml. Calculate the osmotic pressure of the solution.
Added by St11P6-Herbieto, G.
Step 1
First, we need to find the molality of the solution. Molality is defined as the moles of solute per kilogram of solvent. We know that the solution contains 3% phenylalanine by mass, so in 100 g of the solution, there are 3 g of phenylalanine. Show more…
