List of top Chemistry Questions on Colligative Properties

When 3.00 g of a substance of molar mass 250 g mol$^{-1}$ is dissolved in 100 g of CCl$_4$, the boiling point of the solvent (CCl$_4$) will be elevated by _ _ _ K. (rounded off to two decimal places)
The pressure of solution that just prevents the flow of solvent is called:
10g of a nonvolatile solute, when dissolved in 100g of benzene, raises its boiling point by \(1^\circ C\). The molecular mass of the solute in g/mol is (K_b for benzene = 2.53 K·kg/mol):
