2 attempts left Check my work Be sure to answer all parts. A biochemical engineer isolates a bacterial gene fragment and dissolves a 16.0-mg sample in enough water to make 30.0 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? g/mol (b) If the solution density is 0.997 g/mL, how large is the freezing point depression for this solution (K of water = 1.86°C/m)?
A biomedical engineer is working in a lab that is isolating gene fragments. She dissolves a 10.0mg sample in enough water to make 30.0mL of solution. The osmotic pressure of the solution is 0.340torr at 25C. What is the molar mass of the gene fragment? If the solution density is 0.997g/mL, what is the freezing point for this aqueous solution?
