6. a) A student needs about 80 mL of a 0.05 M KIO3 solution to run a reaction. The student has a 100 mL volumetric flask to use in making this solution. How many grams of KIO3 should the student weigh out in order to make this solution? Hint: Think about what volume you can actually measure when using the volumetric flask. b) Given the mass that was measured above, what is the calculated molarity and error of the KIO3 solution from part a? The balance has an error of ± 0.001 grams and the volumetric flask has an error of±0.08 mL.

Here is some information to help. In this experiment, magnesium metal is heated until it reacts with oxygen in the air according to the following balanced equation: 2Mg(s)+ O2(g) → 2MgO(s) (silver metal) (white-gray ash) As the magnesium burns in air, it may also combine with nitrogen in air. To remove any nitride product, water is added, and the product is reheated. Any nitride product is converted to magnesium oxide and ammonia. 3Mg(s)+ N2(g) → Mg3N2(s) Mg3N2(s)+3H2O(l)→3MgO(s)+2NH3(aq) A weighed amount of the magnesium metal is used, and the mass of the oxide product formed is determined at the end of the experiment. The mass of oxygen that combines with the magnesium is obtained from the difference between the mass of the oxide product and the original mass of magnesium. mass of oxide product-mass of magnesium=mass of oxygen in oxide product The empirical formula of the oxide…
