A set of solutions is prepared using 180 g of water as a solvent and 10 g of different non-volatile solutes A, B and C. The relative lowering of vapour pressure in the presence of these solutes are in the order [Given, molar mass of A = 100

g\,\,mo{l^{ - 1}};

B = 200\,\,g\,mo{l^{ - 1}}\,;\,\,C = 10,000\,\,g\,\,mo{l^{ - 1}}]

View answer and explanation

Correct option: C

A > B > C

Option C (

A > B > C

) is correct because the relative lowering of vapor pressure is a colligative property that depends on the number of moles of solute, and A has the most moles for the same mass.
