The amount of sodium per mL was found to be fairly high from a health perspective. The points for the unknowns did not line up precisely with the emission curve for the standards. The solutions contained less sodium than they should have according to the standard emission curve. The absorption values for the unknowns were 22.33 and 36.33 and they should have been about 28 and 41. This could be due to an error in the calculations for determining the amount of soy sauce to use in the preparation of the unknown solutions.
