Moles (amounts of substance)

• Mass


  Moles= mass/ molar mass

  Moles(g)

  Molar mass(g mol^-1)
• Solution 


  Moles= concentration • volume

  Concentration (mol dm^-3)

  Volume (dm^3)
• Gas


  pV = nRT

  p(pressure(Pa))

  V(volume(m^3))

  R(gas constant(8.32 J K^-1 mol^-1))

  T(temperature(K))
