A biochemical engineer isolates a bacterial gene fragment and dissolves a 10mg sample in enough water to make 30ml of solution. the osmotic pressure of the solution is .340 torr at 25 degrees C. the molar mass of the gene fragment is 1.81x10^4 g/mol.
How large is the freezing point depression for this solution?
solution density=.997g/mL
kf of water=1.86 degrees C/m
