Question

An aqueous solution contains 6.89% phenylalanine () by mass. Assume the phenylalanine is nonionic and nonvolatile. Find the freezing point, boiling point, and osmotic pressure of the solution at 25 °C. Assume the solution has a density of 1.00 g/mL.

The molal freezing point depression constant for water, , is –1.86 °C/m. The molal boiling point elevation constant of water, , is 0.5121 °C/m.

Freezing point =  °C ?

Boiling point =  °C ?

Osmotic pressure =  atm?
