Fill in the blank. Boiling point of solution containing a non volatile solute is always ---- the boiling point of pure solvent in which solution is prepared.
If 0.15g of a solute dissolved in 15g of solvent is boiled at a temperature higher by 0.2160C than that of the pure solvent, then the molecular weight of the
substance is (molal elevation constant for the solvent is 2.16):
