Avogadro's number (6.02214076 × 10²³) defines the number of constituent particles (atoms, molecules, or ions) contained in one mole of substance.
Core Principles & Step-by-Step Method
Follow these standard analytical steps to perform instant, error-free calculations:
- 1. Understand that 1 mole is always equal to 6.022 × 10²³ particles.
- 2. To find total particles from moles, multiply moles by 6.022 × 10²³.
- 3. To find moles from particle count, divide total particles by 6.022 × 10²³.
Worked Practical Example
Example: 2 moles of NaCl contains 2 × (6.022 × 10²³) = 1.2044 × 10²&sup4; formula units of sodium chloride.
