NAcid = The
number of moles for the initial quantity of HCl.
Nantacid = The number of moles of HCl
neutralized by Antacid Tablet.
NBase = The number of moles of NaOH
used to neutralize the remaining
HCl (that which was not
neutralized by the antacid).
NAcid = Nantacid + NBase
Nantacid = NAcid - NBase
