Most Important Formulas from Solutions

1. Molarity (M): 

$M = \frac{\text{Number of moles of solute}}{\text{Volume of solution in liters}}$

2. Molality (m): 

$m = \frac{\text{Number of moles of solute}}{\text{Mass of solvent in kg}}$

3. Mole Fraction (χ): 

$\chi_i = \frac{\text{Number of moles of component i}}{\text{Total number of moles in the solution}}$

4. Mass Percentage: 

$\text{Mass \% of A} = \frac{\text{Mass of A in solution}}{\text{Total mass of solution}} \times 100$

5. Volume Percentage: 

$\text{Volume \% of A} = \frac{\text{Volume of A in solution}}{\text{Total volume of solution}} \times 100$

6. Raoult's Law: 

$P_i = x_i \times P_{i}^{\circ}$

7. Henry's Law: 

$P = k_H \times C$

8. Colligative Properties:

1. Relative Lowering of Vapor Pressure (Roult's Law): $\Delta P = P_{\text{pure solvent}} - P_{\text{solution}} = x_{\text{solvent}} \times P_{\text{pure solvent}}$

2. Elevation in Boiling Point: $\Delta T_b = i \times K_b \times m$

3. Depression in Freezing Point: $\Delta T_f = i \times K_f \times m$

4. Osmotic Pressure: $\Pi = i \times C \times R \times T$

9. Van't Hoff Factor (i): 

$\frac{\text{moles of particles after dissociation or association}}{\text{moles of solute initially}}$

10. Ideal Gas Equation: 

PV = nRT

11. Dalton's Law of Partial Pressures: 

$P_{\text{total}} = P_1 + P_2 + \ldots$
