?

Calculations and main tips for revision GCSE C3 Edexcel 360:-

  • To find Moles > Mass/Mr = Moles
  • To find total mass of reactants (products) > Moles (of the given mass) x Mr (of the mass you're trying to find) = Mass (or reactant/product)
  • To find concentration in mol dm^-3 > Moles/Volume (dm^3) = Concentration
  • To find concentration in g dm^-3 > Mass/Volume (dm^3) = Concentration
  • Converting concentration from mol dm^-3 to g dm^-3 (or vice versa) >g dm^-3 = mol dm^-3 x Mr
  • To get the volume of a gas (remember 1 mol of any gas occupies 24
