|---|---|---|
| Topic | Formula | Description |
| Mole Concept | n = m / M | Number of moles (n) equals mass (m) divided by molar mass (M). |
| Molarity (M) | M = n / V | Molarity is moles of solute per litre of solution. |
| Normality (N) | N = Equivalent moles / V | Normality is equivalent moles of solute per litre of solution. |
| Molality (m) | m = n / mass of solvent (kg) | Molality is moles of solute per kilogram of solvent. |
| Ideal Gas Law | PV = nRT | Relationship between pressure (P), volume (V), moles (n), gas constant (R), and temperature (T). |
| Boyle's Law | P1V1 = P2V2 | For a given mass of gas at constant temperature, pressure is inversely proportional to volume. |
| Charles's Law | V1 / T1 = V2 / T2 | Volume of a gas is directly proportional to its temperature at constant pressure. |
| Avogadro's Law | V1 / n1 = V2 / n2 | Equal volumes of gases contain equal numbers of moles at constant temperature and pressure. |
| Raoult's Law | Psolution = Xsolvent x Psolvent | Vapor pressure of a solution is proportional to the mole fraction of the solvent. |
| Osmotic Pressure (π) | π = MRT | Osmotic pressure is the product of molarity (M), gas constant (R), and temperature (T). |
| pH and pOH | pH = -log[H+] | pH is the negative logarithm of hydrogen ion concentration. |
| pOH = -log[OH-] | pOH is the negative logarithm of hydroxide ion concentration. | |
| pH + pOH = 14 | Sum of pH and pOH in aqueous solutions at 25°C. | |
| Nernst Equation | E = E0 - (0.0591 / n) log Q | Calculates cell potential under non-standard conditions. |
| Gibbs Free Energy (ΔG) | ΔG = ΔH - TΔS | Relationship between enthalpy (ΔH), temperature (T), and entropy (ΔS). |
| ΔG = -nFE | Relates Gibbs free energy to cell potential (E). | |
| Arrhenius Equation | k = A e^(-Ea / RT) | Describes the temperature dependence of reaction rates. |
| Hardness of Water | Hardness (mg/L CaCO3) = (Mass of CaCO3 / Volume of water (L)) x 1000 | Measures concentration of calcium carbonate in water. |
| Equivalent Weight | Equivalent weight = Molar mass / Valency | Used in titration calculations. |
