  • concentration (g per dm^3) = mass(g) / volume (dm^3)
  • concentration (mol per dm^3) = n of moles / volume (dm^3)
  • 1 mole of gas at room temp and pressure = 24dm^3
  • % yield= actual mass of product / maximum theoretical mass of product x 100
  • the relative atomic mass is average mass of atoms in an element, taking into account mass and abundance of its isotopes.
  • the relative formula mass is the sum of relative atomic masses of all atoms in the formula.
  • avogado’s constant = 6.02 x 10^23
  • mass = mr x moles
  • the atom economy is the measure of the amount of starting materials that end up as useful products.
  • the limiting reactant is the reactant that is completely used up first and therefore limits the amount of products formed.
  • thermal decomposition is the reaction that occurs when heat is applied to a compound causing it to break down into its different chemical constituents.
