Answer:
The soluble in water are a and b. c is not soluble in water
Explanation:
The water solubility of a compound, it depends its polarity (. KHSO4 has several polar molecules, actually it has ions charged positively like K and H, and charged negatively like sulfate (SO4-2). When it happens, molecules can do hydrogen bridges with water. It is because of above, KHSO4 can be used in wine making. Something similar happens with propylen glycol but in this case the polar part is OH- ions. Benzene has not polar parts. It is totally apolar compound.

Answer:
The osmotic pressure is 24.6 atm
Explanation:
π = M . R . T . i → Formula for osmotic pressure
i = 2 ⇒ NaCl → Na⁺ + Cl⁻
i means Van't Hoff factor, which indicates the numbers of ions dissolved, by the stoichiometry.
R → Universal gases constant
T→ T° in K → T°C + 273 → 25°C + 273 = 298K
π = Osmotic pressure
Let's replace data given ⇒ π = 0.503 mol/L . 0.082L.atm/mol.K . 298K .2
π = 24.6 atm
