Introduction

Aspirin, also known as acetylsalicylic acid, is a widely used medication for pain relief and anti-inflammatory purposes. It is a chemical compound with the molecular formula C9H8O4C_9H_8O_4. In this article, we will explore the relationship between the number of moles of aspirin and the number of moles of oxygen present in the compound.

The Molecular Formula of Aspirin

The molecular formula of aspirin is C9H8O4C_9H_8O_4. This formula indicates that one molecule of aspirin contains 9 carbon atoms, 8 hydrogen atoms, and 4 oxygen atoms. The molecular weight of aspirin can be calculated by summing the atomic weights of its constituent atoms.

Calculating the Molecular Weight of Aspirin

The atomic weights of carbon, hydrogen, and oxygen are 12.01 g/mol, 1.008 g/mol, and 16.00 g/mol, respectively. The molecular weight of aspirin can be calculated as follows:

Molecular weight of aspirin = (9 x 12.01 g/mol) + (8 x 1.008 g/mol) + (4 x 16.00 g/mol) = 108.09 g/mol + 8.064 g/mol + 64.00 g/mol = 180.154 g/mol

The Relationship Between Moles of Aspirin and Oxygen

The molecular formula of aspirin indicates that one molecule of aspirin contains 4 oxygen atoms. Therefore, the number of moles of oxygen present in a given amount of aspirin is directly proportional to the number of moles of aspirin.

Calculating the Number of Moles of Aspirin Containing 0.480 Mol of Oxygen

Let's assume that we have a sample of aspirin containing 0.480 mol of oxygen. Since one molecule of aspirin contains 4 oxygen atoms, the number of moles of aspirin can be calculated as follows:

Number of moles of aspirin = Number of moles of oxygen / 4 = 0.480 mol / 4 = 0.120 mol

Conclusion

In this article, we have explored the relationship between the number of moles of aspirin and the number of moles of oxygen present in the compound. We have calculated the molecular weight of aspirin and used it to determine the number of moles of aspirin containing 0.480 mol of oxygen. The result shows that 0.120 mol of aspirin contains 0.480 mol of oxygen.
