Explain the Avogadro constant as the number of particles in one mole.

In the subtopic The mole and the Avogadro constant, this AQA A-Level Chemistry 7405 learning objective focuses on explain the Avogadro constant as the number of particles in one mole. It belongs to Amount of substance, so revision should stay anchored to this exact subtopic rather than drifting into a generic GCSE-level chemistry summary. Approved keywords to use include mole, particles, Avogadro constant. Avogadro constant. means the number of particles in one mole, approximately 6.022 x 10^23 Avoid the mistake of students often confuse the Avogadro constant with the number of moles instead of recognizing it as the number of particles in one mole; instead, to clarify, remember that the Avogadro constant (6.022 x 10^23) represents the number of atoms, molecules, or ions in one mole of a substance. When calculating the number of particles, use the formula: number of particles = moles × Avogadro constant. For example, if you have 2 moles of a substance, the calculation would be: 2 moles × 6.022 x 10^23 particles/mole = 1.2044 x 10^24 particles For exam answers, remember that the Avogadro constant (6.022 x 10^23) represents the number of particles in one mole. Use this to convert between moles and particles in calculations
