If I titrated 0.0100 M Ce4+ with an unknown substance containing Fe2+ that weighs 0.0249 grams and my equilibrium point is 1.38 mL; How can I find the mmoles of Ce4+ added at the equilibrium point?
Fe2+ + Ce4+ -----> Fe3+ + Ce3+
So far I have 1.50 mL X 0.00001 mmol = 0.000015 mmoles Ce4+ added at equilibrium?
