what is the boiling point of a solution that contains 120g glucose, c6h12o6, dissolved in 0.200kg water? boiling point depression of -1.86 degrees celcious/m

hmmm... the boiling point of a solvent gets higher when something is dissolved in it. so we have boiling point *elevation* not depression. or have i just been brain-hacked?

the reason is that the vapor pressure becomes lower when stuff is dissolved in the solvent. so we have to increase the temperature more than usual to ramp it up to one atmosphere.

the boiling point increase is proportional to the molality. so i would find out the molality of solute particles, assuming that the glucose gets completely dissolved, and then i'd use the constant to find out the increase in boiling point 

hmmm.. celicious.
