Answer:
its D just look on the web
<span>Equivalent millimoles HCl/mg sample = ( (concentration HCl in mmol/mL)(Volume HCl in mL) - (concentration NaOH in mmol/mL)(Volume NaOH in mL) ) / ( (1000 mg/g)(mass antacid sample in grams )
From this equation, then you will be guided.

Moles = Molarity * liters
But if we are calculating millimoles, we may use mL.
Using this:
Moles reacted with antacid = moles of HCl - moles of NaOH
Moles reacted = 0.4548 * 14.1 - 0.1048 * 14.6
Moles reacted = 4.88 millimoles
The mass of the tablet was 1.333 grams = 1333 mg
Millimoles of acid per mg tablet = 4.88/1333
There are about 0.0037 millimoles reacting per milligram of tablet.
