Quantitative chemistry

• abm


  Abbreviation for atomic mass
• Relative molar mass


  The mass of one mole of a substance relative to the mass of one mole of carbon-12
• Desired probu

  The desired product
• Economy total relative molecular


  The total relative molecular mass of all reactants
• Moos


  Abbreviation for moles
• Percentage yield


  The actual yield as a percentage of the theoretical yield
• Percentage yield is always less than 100%
• Theoretical yield


  The maximum amount of product that could be formed from the given amount of reactants
• Concentration


  Measures the amount of the reactant that becomes useful products
• High atom economy is useful because it is cost-effective and environmentally friendly
• Factors that make percentage yield less than 100%

  • Side reactions
  • Incomplete reactions
  • Difficult separation (extraction and waste)
• Quantitative chemistry


  The study of the quantities of substances involved in chemical reactions and the relationships between them
• Conversions


  1. cm³ to dm³

  2. cm³ to m³
• Mr


  Relative molecular mass
• Finding the relative molecular mass (Mr)

  1. Know the relative atomic masses (by number) of the elements in the compound

  2. Multiply the relative atomic masses by the number of atoms in the compound

  3. Add these numbers together
