1. Calculate the molarity of perchlorate ions in a solution prepared by: mixing 289.9 mL of 0.596 M potassium perchlorate with 285 mL of 1.25 M calcium perchlorate.

2. Aqueous potassium iodate and potassium iodide react in the presence of dilute hydrochloric acid, as shown below. KIO3(aq) + 5KI(aq) + 6HCl(aq) ⟶ 3I2(aq) + 6KCl(aq) + 3H2O(l) What is the mass of iodine (in mg) formed when 17.7 mL of 0.097 M KIO3 solution reacts with 24.5 mL of 0.02 M KI solution in the presence of excess HCl(aq)?
