A student performing this experiment weights out 0.6500 grams of an antacid tablet. It is was determined that this tablet contained 0.4655 grams of C a CO3. What is the percent C a CO3 of this tablet? Type your answers without units.

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%
