What is the Mole Concept? Key Definitions & Explanations
Based on Cambridge Classroom's Mole Concept Guide and syllabus-aligned resources, here are concise, exam-centered definitions from our mole concept notes PDF:
- Mole (mol): The SI unit for amount of substance, equal to 6.02 × 10²³ particles (Avogadro's constant, L). Exam Tip: Always use 6.02 × 10²³ for calculations in O Level Chemistry 5070 syllabus.
- Molar Mass (M): Mass of one mole of a substance in grams per mole (g/mol), numerically equal to relative atomic/molecular mass. E.g., For CO₂, M = 44 g/mol.
- Number of Moles (n): n = mass / molar mass (n = m / M) or n = volume / 24 dm³ (gases at RTP). Key for IGCSE Chemistry 0620 worksheets.
- Avogadro's Constant: 6.02 × 10²³ mol⁻¹ – links microscopic particles to macroscopic amounts.
- Stoichiometry: Study of quantitative relationships in chemical reactions using mole ratios from balanced equations.
- Empirical Formula: Simplest whole-number ratio of atoms in a compound, determined from percentage composition.
- Molecular Formula: Actual number of atoms, found by n = empirical formula mass × k, where k = molecular mass / empirical mass.
- Limiting Reactant: Reactant that is completely consumed, limiting product yield.

Essential Formulas from Mole Concept Notes PDF
Download our O Level Chemistry Formula Sheet PDF for quick reference. Here's a summary table:
| Formula | Description | Example |
|---|---|---|
| n = m / M | Moles from mass | 32g O₂ / 32 g/mol = 1 mol |
| n = V / 24 | Moles from gas volume at RTP | 48 dm³ CO₂ / 24 = 2 mol |
| Concentration = n / V (mol/dm³) | Solution concentration | 0.1 mol in 0.5 dm³ = 0.2 mol/dm³ |
| % Yield = (actual / theoretical) × 100 | Reaction efficiency | (8g / 10g) × 100 = 80% |
