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 

where: 

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
