What is the Molar Mass of Aspirin (C9H8O4)?

The molar mass of aspirin (C₉H₈O₄) is calculated by summing the atomic masses of all the atoms in its chemical formula. Here’s how it’s done:

• Carbon (C): 9 atoms × 12.01 g/mol = 108.09 g/mol
• Hydrogen (H): 8 atoms × 1.008 g/mol = 8.064 g/mol
• Oxygen (O): 4 atoms × 16.00 g/mol = 64.00 g/mol

Adding these together:

108.09 g/mol + 8.064 g/mol + 64.00 g/mol = 180.154 g/mol

Therefore, the molar mass of aspirin is 180.154 g/mol.
