Definition of Acetylsalicylic Acid and Its Chemical Structure

Acetylsalicylic acid, commonly known as aspirin, serves as a nonsteroidal anti-inflammatory drug (NSAID). It alleviates pain, reduces inflammation, and lowers fever, making it widespread in both prescription and over-the-counter medications.

The chemical formula for acetylsalicylic acid is C₉H₈O₄, indicating it consists of nine carbon atoms, eight hydrogen atoms, and four oxygen atoms. This compound features a distinctive structure that contributes to its pharmacological properties.

• Functional Groups:
  • Acetyl group (-COCH₃)
  • Carboxylic acid group (-COOH)

The arrangement of these groups creates a benzene ring, which is central to the molecule’s stability and reactivity. The acetyl group increases the drug’s lipophilicity, facilitating its absorption in the body.

Understanding this structure aids in studying its mechanism of action, where acetylsalicylic acid inhibits cyclooxygenase (COX) enzymes, leading to decreased production of prostaglandins involved in inflammation and pain signaling.

In summary, acetylsalicylic acid’s specific molecular configuration and functional groups play a significant role in its therapeutic effects, making it a fundamental medication in many clinical settings.

Calculation of Acetylsalicylic Acid Molar Mass

To calculate the molar mass of Acetylsalicylic Acid (commonly known as Aspirin), add the atomic masses of all atoms in its molecular formula, C₉H₈O₄.

Step-by-Step Calculation

1. Identify the elements in the formula: Carbon (C), Hydrogen (H), and Oxygen (O).

2. Use the atomic masses: Carbon (C) = 12.01 g/mol, Hydrogen (H) = 1.01 g/mol, Oxygen (O) = 16.00 g/mol.

3. Multiply the number of atoms of each element by their respective atomic masses:

     – Carbon: 9 atoms × 12.01 g/mol = 108.99 g/mol

     – Hydrogen: 8 atoms × 1.01 g/mol = 8.08 g/mol

     – Oxygen: 4 atoms × 16.00 g/mol = 64.00 g/mol

Total Molar Mass

Now, sum these values:

108.99 g/mol + 8.08 g/mol + 64.00 g/mol = 181.07 g/mol.

The molar mass of Acetylsalicylic Acid is 181.07 g/mol.
