A solution is prepared by dissolving 1.50 g of compound in 25.0 mL H20 at 25 degrees Celsius. The boiling point of the solution is 100.45 degrees Celsius.
a) What is the molar mass of the compound if it is non-volatile nonelectrolyte and the solution behaves ideally? (d of H20 at 25 degrees Celsius = 0.997 g/mL)
b) Independent conductivity measurements indicate that the compound is actually ionic with general formula AB2 or A2B. What is the molar mass of the compound if the solution behaves ideally?
c) Compositional analysis indicates an empirical formula of CaN206. Calculate the van't Hoff factor i for this solution.
