(A) Raoult's Law (II): This law states that the partial vapor pressure of a component in an ideal solution is equal to the vapor pressure of the pure component ($p_1^\circ$) multiplied by its mole fraction ($x_1$).
- Expression: $p_1 = x_1 p_1^\circ$
(B) Dalton's Law of Partial Pressures (I): This law states that the total pressure exerted by a mixture of non-reactive gases is equal to the sum of the partial pressures of the individual gases.
- Expression: $P_{\text{total}} = p_1 + p_2$
(C) Henry's Law (IV): This law states that the partial pressure of a gas in the vapor phase ($p$) is proportional to the mole fraction of the gas ($x$) in the solution.
- Expression: $p = K_H x$
(D) Osmotic Pressure (III): For a dilute solution, osmotic pressure ($\Pi$) is directly proportional to the molar concentration ($C$) of the solute at a given temperature ($T$).
- Expression: $\Pi = CRT$
