An antacid tablet weighing 1.462 grams was dissolbed in 25mL of 0.8M HCl and diluted with water. The excess HCl was titrated with 3.5 mL of 1.019M NaOH solution.

1. Calculate the number of millimoles added to the tablet
2. Calculate the number of millimoles of NaOH required to neutralize the excess HCl left over
3. Calculate the number of millimoles of HCl that neutralized the tablet.
