Answer the following five questions using the nine steps below and show all work. I realize this is a lot so if you answer it correctly I will post 3 possibly 4 dummy questions for you and then you can just answer them with anything and I will give a lifesaver rating. Thanks in advance

1. Using the calibration equation and the absorbance you measured for the prepared sample, calculate the ferroin concentration. Show your work and don't forget to include units.

2. Based on the procedural steps and the ferroin concentration you just calculated, calculate the moles of ferroin in the final ferroin complex solution prepared in Part II, Step 9. Show your work.

3. Based on the moles of ferroin in the final ferroin complex solution, calculate the moles of iron in the crushed tablet solution prepared in Part II, Steps 2-5. Show your work.

4. Using the "moles of iron in the crushed tablet solution" you just calculated, calculate the mass (in mg) of iron in the crushed sample that you weighed out. Show your work.

5. From the mass of iron in the crushed tablet sample you weighed out, calculate the mass (in mg) of iron in a whole tablet. Show your work.

y=12560x-0.073

Crushed Tablet Iron used: .023 g

Absorbance .08

Mg of iron per tablet as listed on the bottle: 436
