A set of solutions is prepared using180 gof water as a solvent and10 gof different non-volatile solutesA, BandC. The relative lowering of vapour pressure in the presence of these solutes are in the order [Given, molar mass ofA=100 g mol-1 ; B=200 g mol-1 ; C=10,000 g mol-1]

Options:

Answer:
C
Solution:

Number of moles = wtgmMW=10MW

Relative lowering in vapour pressure depends on no. of mole of solute greater the no. of moleof solute greater in RLVP and smaller will be vapour pressure.

So order of vapour pressure is A>B>C.
