Step 4:Use this information to do any final calculations necessary.

The final step in this process is dependent on the problem. The goal of this problem is to find out what percentage of the antacid tablet is the active ingredient, calcium carbonate. You have already determined that the tablet contains 0.73 grams calcium carbonate. Since the original tablet had a total mass of 1.00 g, it is easy to calculate the percentage of calcium carbonate in the tablet.

What percentage of the antacid tablet is calcium carbonate?
