Answer to Question #318927 in General Chemistry for Sassy

Question

1.An organic compound is known to be nonvolatile and non electrolyte.A 0.35-g sample is dissolved in water and diluted to 150mL.The osmotic pressure is measured as 0.04 atm at 25°C.The approxulmate mass number for this compound is 1400g/mol.From the data provided in this problem and knowing that the density of the solution is 1.00g/mL.

a.Calculate the freezing point of the solutions.

b.Determine if the freezing point change would be a good way to determine the molecular mass of the compound.

c.Would the boiling point change be a better determining factor than the freezing point change?
