Answer to Question #184949 in Electric Circuits for jenifer

Question

Solve and Explain briefly:

An organic compound is known to be non-volatile and non-electrolyte. A 0.5-g sample is dissolved in water and diluted to 160 mL. The osmotic pressure is measured as 0.05 atm at 30°C. The approximate mass number for this compound is 1500 g/mol. From the data provided in this problem and knowing that the density of the solution is 1.00 g/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?
