Answer:

The percent of C is equal to 71.62%, the percent of O3 is equal to 28.38%

Explanation:

To find the percentage of C, you just have to divide the amount in grams of C, on the weight of the tablet and multiply it by 100, so that the answer is in percentage, as follows:

%C = (0.4655 g C/0.65 g antacid tablet) x 100 = 71.62%

%O3 = 100 - 71.62 = 28.38%
