If 0.15 g of a solute dissolved in 15 g of solvent is boiled at a temperature higher by 0.216∘C than that of the pure solvent. The molecular weight of the substance (molal elevation constant for the solvent is 2.16 ∘C kg/mol) is

The molal elevation constant of water = 0.52 k/m . The boiling point of 1.0 molal aqueous KCl solution (assuming complete dissociation of KCl) should be
