16 Calculate the number of moles of NaOH titrant that you added to four signi cant gures using molarity and volume. This is the number of moles of HCl neutralized by the NaOH. 17 Determine the number of moles of HCl not neutralized by the NaOH to four signi cant gures. This is the number of moles of HCl neutralized by the antacid.

As an antacid, magnesium hydroxide is dosed at approximately 0.5–1.5 g in adults and works by simple neutralization, where the hydroxide ions from the Mg(OH)2 combine with acidic H+ ions produced in the form of hydrochloric acid by parietal cells in the stomach to produce water. No. of moles of HCl per gram antacid: 0. 0057 i?? 0.

Apr 23, 2018  · How to Calculate Mmol. system of measurement defines a millimole (Mmol) as one-thousandth of a mole. You generally calculate the number of moles of a substance by weighing the amount you have on hand. If you want to convert to Mmol, so divide the number of moles by 2.5 to get the molarity: 0.0015 ÷ 2.5 = 0.0006 M.
