Determine the boiling point elevation of H2O in the following solution
a 2.5 m solution of C6H12O6 in H2O
All i need is the formulas because i don't know how to solve it
Thank you
:l

Chemistry 
DrBob222,
moles = grams/molar mass.
Calculate moles C6H12O6.
m = moles/kg solvent.
Calculate m of the solution.
Delta T = kb*m
Calculate delta T. 
Chemistry 
Veronica,
O.o where do i get the grams from m=grams/molar mass?

Chemistry 
DrBob222,
You don't and you don't need that step or the next one. I just included them because most problems require the three steps. In this case, you already have molality given so you already have the first two. Just substitute into the third step, delta T = Kb*m.
