CIE A Level Chemistry复习笔记3.1.4 Molecular & Empirical Formulae

• The molecular formula shows the number and type of each atom in a molecule
  • Eg. the molecular formula of ethanoic acid is C₂H₄O₂
• The empirical formula shows the simplest whole number ratio of the elements present in one molecule of the compound
  • Eg. the empirical formula of ethanol is CH₂O
