Copper has two naturally occurring isotopes. Cu-63 has a mass of 62.939 amu and relative abundance of 69.17%. Use the atomic weight of copper to determine the mass of the other copper isotope.
we then titrated both the aqueous and organic layer. for organic layer, we used 0.1M (S2O3)2- for aqueous layer, we used 0.01M (S203)2- find concentration [I]2 (subscript 2) for aqueous and organic layer
