Aqueous potassium iodate (KIO_3) and potassium iodide (KI) react in the presence of dilute hydrochloric acid, according to the following equation: KIO_3(aq) + 5 KI(aq) + 6 HCI(aq) rightarrow 3 I_2(aq) + 6 KCI(aq) + 3 H_2O(l) What mass of iodine (I_2: M = 253.81 g/mol) is formed when 50.0 mL of 0.020 M KIO_3 solution reacts with an excess of KI and HCI? 0.13gI_2 0.25 gI_2 0.38 gI_2 0.76 gI_2 None of the above
