basic chemical quantities

  • moles = mass/molar mass
  • moles = (volume x concentration) / 1000
  • volume = moles x molar volume
    • at room temperature and pressure, molar volume is 24dm^3
  • number of entities = moles x 6.023x10^23 {this is the Avogadro constant}
  • concentration = mass of solute / volume of solution
  • concentration = moles of solute / volume of solution
  • % yield = (actual yield / theoretical yield) x 100
  • atom economy = (mass of atoms in product / mass of atoms in all reactants) x 100

energetics

  • E = mcΔT
  • ΔH = energy / moles
