Okay so the five volumetric flasks came from solutions that the professor told us to get the wavelength for the highest point of absorbance for asked how I got the highest point of absorbance earlier

Answer 1

and the 0.077 was set to that because that was the lowest number I could get on spectrometer... that's why in the discussion part it said that is why there might be some error.

Answer 2

OK on the 0.077. That is a very good reason why the answer may have been a little low but I still would say that some of the iron may have been lost in the transfer from the crucible. For the five volumetric solutions, I assume the prof gave you the solutions to use. I would stick one statement in somewhere, you pick the place, something like this. Several dilutions were provided and the spectrum was scanned from ??nm to ??nm in order to identify the maximum absorbance. It was determined that the maximum absorbance was at ??nm. (I saw you had that (310 nm or something like tht) but I have forgotten exactly where it was placed. That spot may be the appropriate spot to place this statement.

Answer 3

It is still placed into the methods part
