5. In the laboratory, a student dilutes 28.2 mL of a 9.43 M hydroiodic acid solution to a total volume of 300.0 mL. What is the concentration of the diluted solution in M? 6. How many milliliters of 9.92 M hydroiodic acid solution should be used to prepare 5.50 L of 0.100 MHI in mL?

7. A 0.5435 g sample of a pure soluble chloride compound is dissolved in water, and all of the chloride ion is precipitated as AgCl by the addition of an excess of silver nitrate. The mass of the resulting AgCl is found to be 1.1429 g.

What is the mass percentage of chlorine in the original compound? %

8.A student determines the calcium content of a solution by first precipitating it as calcium hydroxide, and then decomposing the hydroxide to calcium oxide by heating. How many grams of calcium oxide should the student obtain if his solution contains 57.0 mL of 0.577 M calcium nitrate?
