  • eqations you need to know ofr unit C5
    • amount of moles = contration* volume
    • conc=amount of moles /vol
    • vol=amountof moles/conctration
    • no of moles=mass/molar mass
    • how to do a empirical formulae  equation divide the amount by its MR to get the to number then get the smallest number say you divide h20 with 50% oxygen and 25% hydrogen so 50/1 = 50 25/ 16 =1.5625 you would divide both of these numbers by 1.5625 to get the number then you work this out in a ratio  for water 2 hydrogen to one oxygen giving H2o
