Equations

• Number of particles

  Number of moles * Avogadro's constant
• Mass / Mr = Moles.
• Atom economy

  Atom economy = mass of wanted product from equation

  --------------------------------------- x 100

  total mass of products from equation
• Concentration (c) = Mass / Volume (dm3)
• Percentage yield = Actual yield / Theoretical yield x 100%
• Theoretical yield = Atomic mass of reactant x amount of reactant used (in mol).
• Ideal gas equations


  PV = nRT

  p = pressure in Pascals

  V = volume in m3

  T = temperature in Kelvin

  n = moles

  m = mass in grams
• Mass / Mr = Moles
• Concentration ( moldm^-3) / volume (dm^-3 ) = mols
• Conversions
