The salt content was extracted from a 12.0000 g junk food sample. The extract was diluted to 100.00 mL. From this solution, 15.00 mL was taken and required 23.75 mL of a 0.08943 M AgNO3 solution to reach the endpoint. What is the percentage by mass of salt as NaCl (58.45 g/mol) in the junk food sample?
