    Hello... I was wondering if anyone could help...

    I am currently on a SKE and all the experiments and questions I have got but this one for some reason is not going well...

    I have attached the Salters A level iodine clock experiment...

    The questions at the bottom I am stuck on....

    Question 1-3 I can do

    Question 4 and 5 I can't.... anyone know how I work them out?

    The answers are:

    4. 8 x 10-5 mol
    5a 2 x 10-5 mol S2O3^2-
    5b 1 x 10-5 mol I2
    5c 12.5%

    If anyone could help that be greatly appreciated?
