Can someone help with question 2 of part A? Thank you

1. You will be using several compounds this week that have polyatomic ions with which you are unfamiliar: the thiosulfate ion: S2O32 and the iodate ion IO3. Write a table that has the correct formula and name for each of the following: sodium thiosulfate, potassium iodate, potassium iodide, sulfuric acid. 2. In this experiment you will be calculating concentrations of individual ions in aqueous solution. For example, a 1M solution of potassium iodide gives rise to a solution that is 1M in potassium ions and 1M in iodide ions. Sulfuric acid is a DIPROTIC ACID. which gives rise to 2 moles H+ ions for each mole of acid. For each compound you have listed above, show the ion and the number of each ion that will occur in aqueous solution. Ex. H2SO42H+(aq)+SO42(aq) 3. Sodium thiosulfate is a hydrated compound containing five water molecules. Calculate the amount of hydrated sodium thiosulfate necessary to make 500ml of 0.025M solution (remember that the water molecules are included in the molecular weight of hydrated compounds). 4. How many moles of potassium iodate are in 0.2124g ? 5. If the 0.2124 of potassium iodate are dissolved to make 250ml of solution what is the molarity? 6. If you remove a 25ml aliquot of potassium iodate from the 250ml of solution, a. How many moles potassium iodate is this? b. How many moles of iodate ions is this
