Im stuck on these few questions that seems to be getting me no where :

c HCl = 0.1812
c NaOH = 0.1511
volume of HCl added : 75
volume of NaOH added: 29.23,19.58,33.3
-Determine the number of mmoles of HCl that did not react with the anatacid.
- mmoles of HCl neutralized by the tablet?
- mmoles of H+ neutralized per gram of antacid(mmole/g)
- Average #mmoles of H+ neutralized per gram of anatacid
