A biochemical engineer isolates a bacterial gene fragment and dissolves a 14.0 mg sample of the material in enough water to make 34.5 mL of solution. The osmotic pressure of the solution is 0.340 torr at 25°C.
A) What is the molar mass of the gene fragment? Answer in: g/mol
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)? Answer in: Celcius degree
