Calculating its molar mass is straightforward once you know the atomic masses of carbon ©, hydrogen (H), and oxygen (O). Let’s dive into the step-by-step process to determine the molar mass of C7H6O3 efficiently.

What is Molar Mass and Why is it Important?

Molar mass represents the mass of one mole of a substance and is expressed in grams per mole (g/mol). It is a fundamental concept in chemistry, crucial for balancing chemical equations, determining reaction yields, and understanding molecular structures. For C7H6O3, calculating its molar mass helps in precise measurements and accurate experimental results.

Step-by-Step Calculation of the Molar Mass of C7H6O3

To calculate the molar mass of C7H6O3, follow these simple steps:

1. Identify the Atomic Masses

   • Carbon ©: 12.01 g/mol
     
   • Hydrogen (H): 1.01 g/mol
     
   • Oxygen (O): 16.00 g/mol
     

2. Count the Atoms in the Formula

   • Carbon ©: 7 atoms
     
   • Hydrogen (H): 6 atoms
     
   • Oxygen (O): 3 atoms
     

3. Multiply Atomic Masses by Atom Counts

   • Carbon: 7 × 12.01 = 84.07 g/mol
     
   • Hydrogen: 6 × 1.01 = 6.06 g/mol
     
   • Oxygen: 3 × 16.00 = 48.00 g/mol
     

4. Sum the Results
   Total molar mass = 84.07 + 6.06 + 48.00 = 138.13 g/mol

📌 Note: Always double-check atomic masses and calculations to ensure accuracy.
