What is the molar mass of salicylic acid?

Salicylic acid is an organic compound with the chemical formula C₇H₆O₃. To calculate its molar mass, you need to sum the atomic masses of all the atoms in the molecule.

Here’s the breakdown:

• Carbon (C): 12.01 g/mol × 7 = 84.07 g/mol
• Hydrogen (H): 1.01 g/mol × 6 = 6.06 g/mol
• Oxygen (O): 16.00 g/mol × 3 = 48.00 g/mol

Now, add these values together:

84.07 g/mol + 6.06 g/mol + 48.00 g/mol = 138.13 g/mol

Therefore, the molar mass of salicylic acid is approximately 138.13 g/mol.
