What is the dilution formula? I have not learned this,

  • Chemistry -

    c1v1 = c2v2
    c = concn
    v = volume

    For example.
    You have 2M NaOH and you want to make 500 mL of 0.25M. How much of the 2M stuff do you take?
    2M*x mL = 0.25M*500 mL
    mL = (0.25*500/2) = 62.5 mL

    So you take 62.5 mL of 2M NaOH, add to 500 mL volumetric flask and make to the mark. This will give you 500 mL of 0.25M NaOH.
