A biochemical engineer isolates a bacterial gene fragment and dissolves a 14.7 mg sample of the material in enough water to make 36.5 mL of solution. The osmotic pressure of the solution is 0.340 torr at 25°C.
a. What is the molar mass? 2.20e4
b. If the solution density is 0.997 g/mL, how large is the freezing point depression for this solution (Kf of water=1.86°C/m)
