Question

How would you find Fe in mol Fe/L if you have the mg Fe/mL. I dont believe my answer for it is correct.

Absorbance +Raw data: Volume of 0.04 mg/mL Fe standard 10 mL 5 mLs 2 mLs 1 mLs 7 Fe concentration (mg Fe/mL) 0.004 mg/mL 0.002 mg/mL 0.0008 mg/ml 0.0004 mg/mL Fe concentration (mol Fe/L) .183 x 10 mol 3.581 x 10 mol 1.433 x 10 mol 7.16 x 10 mol 0.013 0.068 0.327 0.718
