Question

2 g of a non-volatile non-electrolyte solute is dissolved in 200 g of two different solvents A and B whose ebullioscopic constants are in the ratio of 1:8. The elevation in boiling points of A and B are in the ratio  (x:y). The value of y is  (Nearest Integer)

Canvas Classes · Accepted Answer

Strategy:
 Since the mass of solute, molar mass, and mass of solvent are the same for both cases, the elevation in boiling point () will be directly proportional to the ebullioscopic constant ().

Step 1: Establish the proportionality
. For the same molality :

Step 2: Use the given ratio
Given .

Thus, , which means .
