A set of solutions is prepared using 180 g of water as a solvent and 10 g of different nonvolatile 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 mol–1; B = 200 g mol–1; C = 10,000 g mol–1]

Question

A set of solutions is prepared using 180 g of water as a solvent and 10 g of different nonvolatile 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 mol^–1; B = 200 g mol^–1; C = 10,000 g mol^–1]

A > C > B

C > B > A

A > B > C

B > C > A
