You are given a 1.56-g mixture of sodium nitrate and sodium chloride. You dissolve this mixture into 127 mL of water then add an excess of 0.537 M silver nitrate solution. You produce a white solid, which you then collect, dry, and measure. The white solid has a mass of 0.501 g.
(a) If you had an extremely magnified view of the remaining solution to the atomic-molecular level, list the major species you would see. (Include charges, if any. Use the "," character to separate substances. Omit states-of-matter from your answer.)
(b) Calculate the percent sodium chloride in the original unknown mixture.
