Dive into the world of equations along with JEE Main Chemistry Revision notes and amplify your study sessions. Explore our Chemistry formula pages to start your preparation journey of JEE Main today!

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: 

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