Question- 1) If you are using 5.25% (mass/mass) bleach solution and you determine that the density of the bleach solution is 1.08 g/mL, how many moles of sodium hypochlorite are present in a 4.00 mL sample?

2) You will prepare a "working" 1,10-phenanthroline solution by diluting a small volume of the standard 1,10-phenanthroline solution with DI water to a total volume of 50.00 mL. You will then add Fe2+ to the diluted phenanthroline solution in small increments and use a colorimeter to monitor the colored product that is created. If you used 2.0 mL of a standard 1,10-phenanthroline solution, in which the concentration of phenanthroline is 3.6 x 10-3 M, to prepare your "working" solution, how many moles of 1,10-phenanthroline are available to react with the iron ions?

Show all work, use additional paper if necessary.
