Question

explain the solution.

Answer 1

I think it should be option 1 as decimolar means 1/10th of a molar solution.
now, M=n/V
1/10=n/V
V=10n
so let's assume given mass anything say X.
V=10*X/M
M is molecular mass
now V is inversely proportional to the molecular mass so high molecular mass means low volume.
we want less volume as osmotic pressure potential will be greater if solutes are less.
so highest molecular mass compound Will be the answer

Answer 2

Answer:

solutions is mixture of different particles
