Oct 13, 2025 by miodeya.com 109 views

Introduction

Vitamin C, also known as ascorbic acid, is an essential nutrient found in various foods and supplements. In this article, we will calculate the mass percent of vitamin C in a tablet containing 0.0109 mol of ascorbic acid. To do this, we need to know the molar mass of ascorbic acid and the mass of the tablet.

Calculating Molar Mass of Ascorbic Acid

The molar mass of ascorbic acid ( $C_6H_8O_6$ ) is given as $176.12 \, \text{g/mol}$ . This value represents the sum of the atomic masses of all the atoms in the molecule.

Calculating Mass of Ascorbic Acid

To calculate the mass of ascorbic acid in the tablet, we can use the formula:

mass = number of moles × molar mass

Plugging in the values, we get:

mass = 0.0109 mol × 176.12 g/mol = 1.918 g

Calculating Mass Percent of Ascorbic Acid

To calculate the mass percent of ascorbic acid in the tablet, we need to divide the mass of ascorbic acid by the total mass of the tablet and multiply by 100.

mass percent = (mass of ascorbic acid ÷ total mass of tablet) × 100

Plugging in the values, we get:

mass percent = (1.918 g ÷ 2.70 g) × 100 = 71.0%

Conclusion

In this article, we calculated the mass percent of vitamin C in a tablet containing 0.0109 mol of ascorbic acid. We found that the mass percent of ascorbic acid in the tablet is 71.0%. This value represents the percentage of the tablet that is composed of vitamin C.

Discussion

The mass percent of a substance in a mixture is an important concept in chemistry. It represents the percentage of the mixture that is composed of the substance. In this case, the mass percent of ascorbic acid in the tablet is 71.0%, which means that 71.0% of the tablet is composed of vitamin C.

Calculating Mass Percent of Other Substances

To calculate the mass percent of other substances in the tablet, we can use the same formula:

mass percent = (mass of substance ÷ total mass of tablet) × 100

For example, if we want to calculate the mass percent of water in the tablet, we can use the following formula:

mass percent = (mass of water ÷ total mass of tablet) × 100

Assuming that the tablet contains 0.5 g of water, we can plug in the values to get:

mass percent = (0.5 g ÷ 2.70 g) × 100 = 18.5%

Conclusion

In this article, we calculated the mass percent of vitamin C in a tablet containing 0.0109 mol of ascorbic acid. We also discussed the concept of mass percent and how to calculate it for other substances in a mixture. The mass percent of a substance in a mixture is an important concept in chemistry and can be used to determine the composition of a mixture.
