A sample of antacid tablet that contains NaHCO3 is analyzed in the lab. The student dissolves 1.50g tablet in 35.0 mL of HCl solution containing 0.0300 mole of HCl. The back-titration of the excess HCl require 10.5 mL of 2.05M NaOH solution. 1) If that tablet label showed that each tablet contains 0.950 gram of NaHCO3. Determine the percent error in the student experiment. 2) Calculate the mass percent of the NaHCO3 in the tablet
