Not sure to go about solving this, if someone could explain how to go about this, I would very much appreciate it! Thanks!
A tablet is expected to be 30.8% citric acid (H3C6H5O7) and 10.1% aspirin. How much citric acid would be required to exactly react with all of the sodium bicarbonate in one Alka-Seltzer tablet?
hint: citric acid is triprotic, 3 H+'s per molecule. You need to re-balance the reaction equation (original equation: NaHCO3 + HCl --> H2O + CO2 + NaCl ).
hint: you will need to calculate the average mass of an Alka-Seltzer tablet.
