Question

Answer 2

This probably should have been posted in the Chemistry section. but I'll answer it here.

0.04 L (0.12 mole/L) = 0.0048 moles of HCl.  This will neutralize 0.0048 moles of NaHCO3.  The molar mass of NaHCO3 is 84.  So 84gm/mol x 0.0048 moles = 0.1 grms.  So there will be approximately 400 mg of NaHCO3 in the 500 mg tablet.

Answer 3
