📚 Mole Concept — Exam-Centered Definitions (Concise)
- Mole: The amount of substance containing 6.02 × 10²³ particles (Avogadro constant).
- Molar Mass (g/mol): Mass of one mole of a substance.
- Moles Formula: n = mass ÷ molar mass.
- Mole Ratio: Ratios of moles in a balanced chemical equation.
- Avogadro’s Law: Equal volumes of gases at same conditions contain equal numbers of molecules.
- Molar Volume: 24 dm³ at room temperature & pressure (RTP).
- Concentration (mol/dm³): Moles of solute ÷ volume of solution in dm³.
- Empirical Formula: Simplest whole-number ratio of elements.
- Molecular Formula: Actual number of atoms of each element.

❓ FAQs
1. What is the purpose of moles?
Moles allow chemists to count particles using mass. Without moles, chemical equations cannot be used accurately.
2. Are moles always circular? (Trending Query)
In chemistry, “moles” are units, not skin marks. So no — chemistry moles have no shape.
3. Does “M” stand for moles?
In most equations, “n” represents moles. “M” usually means molarity.
4. What is g/mole?
It is the unit for molar mass.
5. Can I use these notes for A Level?
Yes — especially Cambridge 9701, Edexcel 9CHO, YCH11, AQA 7405 and Oxford AQA.
