Answer to Question #326729 in General Chemistry for Justin

Question

1. Which is not a colligative property? *

A. Freezing point depression

B. Boiling point elevation

C. Osmotic Pressure

D. Vapor pressure

2. Which is correct about the boiling point of a 1 m aqueous solution of sucrose (342 g/mol) and a 1 m aqueous solution of ethylene glycol (62 g/mol)? Considering that both solutions are non-electrolyte. *

A. sucrose solution boils at higher temperature as it has more solute particles than ethylene glycol solution

B. ethylene glycol solution boils at higher temperature as it has less solute particles than sucrose solution

C. exhibit the same boiling point because each solution has one mole of solute particles (molecules) per kilogram of solvent.

D. ethylene glycol solution and sucrose solution when exposed at higher temperature has both equal amount of solute particles per kilogram of solvent.
