An aqueous solution that contains 115.662 g of a nonvolatile
nondissociating solute in 1125 g of water boils at 102.50 0
C. What is the
molar mass of the solute?
STEP BY STEP EXPLANATION PLEASE
The change in boiling point of the solvent above a solution from that of the pure solvent is directly proportional to the molal concentration of the solute:
deltaT = Kbm
deltaT is the change in boiling point of the solvent,
Kb is the molal boiling point elevation constant For water Kb=0,512°C/m , and
m is the molal concentration of the solute in the solution.
first if all we need to find the number of moles of the solute
