Okay so I got the 39% from 5 runs on the spectrometer from volumetric flasks from 100-500 mL filled just sodium acetate,hydroxylamine hydrochloride

and phenanthroline and distilled water all this was put into those flasks before my iron solution the professor wanted us to do this so we could see the wavelength on the spectrometer

If you did a wavelength scan on the spectrometer to see where the maximum was, then that should be included in the discussion. If you had 5 runs, then you should include the values obtain with each run, then show the average and give some kind of precision, either percent or whatever your prof wants.

So should it also be introduced into to the methods part to since I had to do that as part of my methods. And you want me to put the equations into my discussion part of the lab report of each run the equations are y=mx+b or should I put that in the result part

I would put the scan part in the methods and explain in some detail what you did. In the discussion part you will want to give thre results; i.e., where the minimun and maximum was and what you used. You may want to include, also, WHY you used the maximum absorbace for that wavelength and not some other wavelength that you could have picked.

To calculate the percentage concentration of a solution, you need to know the amount of solute (sodium acetate and hydroxylamine hydrochloride) and the volume of the solution. Here's how you can calculate the percentage concentration:

1. Determine the total mass of solute (sodium acetate + hydroxylamine hydrochloride) used in the 5 runs. Let's assume you used 'x' grams of solute in total.

2. Calculate the total volume of the solution used in the 5 runs. If you used volumetric flasks ranging from 100 mL to 500 mL, you need to add the volumes together. Let's assume you used 'y' mL (milliliters) of solution in total.

3. Now, you can calculate the concentration in grams per milliliter (g/mL) by dividing the total mass of solute (x grams) by the total volume of the solution (y mL).

Concentration (g/mL) = Total mass of solute (g) / Total volume of solution (mL)

4. Multiply the concentration by 100 to convert it to a percentage:

Percentage concentration = Concentration (g/mL) * 100

Using the above steps, you can calculate the percentage concentration of the solution. Simply substitute the values of 'x' (total mass of solute) and 'y' (total volume of solution) that you obtained from the 5 runs into the equations, and you will find the percentage concentration.
