Important information about Molar concentrationsCalculate the molar concentrations, I-, disulfur octaoxide, disulfur trioxide.From [stock concentrations] 15 ml of .20 M potassium iodine, 20 ml of .10M K2S2O8, and 10 ml of .0050M Na2S2O3, I am supposed to figure out the molar concentrations of I-, disulfur octaoxide, and disulfur trioxide.
First I thought just use the concentration and volume of each stock concentration to find the moles...but I got stock. How do I use the information I wrote down to figure how to find the molar concentrations of the above
