Answer choices:
The solution of A will freeze at a lower temperature than thesolution of B.
The solution of A will have a higher osmotic pressure than thesolution of B.
The vapor pressure of the two solutions will be equal.
The boiling point of solution A will be lower than the boilingpoint of solution B.
The vapor pressure of solution A will be lower than the vaporpressure of solution B.
