Question

QUESTION:

1) WHICH ANTACID IS MORE EFFECTIVE?

-----AVERAGE ACTIVE MOLES PER GRAM FOR ROLAIDS IS .00575

-----AVERAGE ACTIVE MOLES PER GRAM FOR TUMS IS .00928

Mass of flask (g) Mass of flask + antacid (g) concentration of HCl (mL) Volume of HCl (mL) Concentration of NaOH (M) Initial volume of NaOH (mL) Final volume of NaOH (mL) Moles of HCl added Moles of NaOH added Active moles of antacid Grams of antacid (g) Active moles of antacid per gram Average active moles per gram Mass of flask (g) Mass of flask + antacid (g) concentration of HCl (mL) Volume of HCl (mL) Concentration of NaOH (M) Initial volume of NaOH (mL) Final volume of NaOH (mL) Moles of HCl added Moles of NaOH added Active moles of antacid Grams of antacid (g) Active moles of antacid per gram Average active moles per gram

Explanation / Answer

Highere the average moles per gram, higher the activity.

Therefore average active moles per gram for tums is more active.
