1.)What is the boiling point of the water in your radiator if 2.00kg of antifreeze is added to 9.00 * 10^3 grams of water?

2.)Assuming that each system behaves ideally, which solution (0.25 m KCl or 0.25 m C3H8O3)would have the lower freezing point? Explain.

My answer: I say that C3H8O3 would have the lower point because of hydrogen??? right or wrong

3.)Is the following statement true or false: "Dissolving a nonvolatile solute in a solvent has the effect of extending the temperature range over which the solvent remains in the liquid phase." Explain.

My answer: I say this statement is true.????
