An analysis of generic antacid tablets labeled to contain 250mg of CaCO3 (MM= 100.09g/mol) per tablet of active ingredient was performed. The analysis was performed by dissolving a 0.550g sample of the antacid tablet in 75.00mL of 0.1055M HCl. The excess acid was back-titrated with exactly 44.97mL of 0.125M NaOH. The average weight of a tablet is 1.045g. The tablet came from a bottle of 125 tablets that cost $3.49.
Calculate the actual mg per tablet of CaCO3 in the generic antacid.
