If 1 antacid tab neutralizes 6.84 mmol of HCL (36.46 g/mol). How many tabs are needed to neutralize 125 mL of stomach acid. Assume [H3O+] = 0.10 mmol/mL.
I have no idea where to go with this. Any formula would help

1. How much acid do you have in 125 mL of 01M acid? That's 125 mL x 0.1M = 12.5 mmols.
6.84 mmols/tab x # tablets = 12.5 mmols.
Solve for # tablets

2. Thanks so much. I had come up with 12.5 mmols, but didn't know what to do with it.

Instead of using ratios for back titrations we can also use molarities if our solutions are standardized. A 0.188g sample of antacid containing an unknown amount of triprotic base Al(OH)3 was reacted with 25.0mL of 0.101M HCl. The
