Practical Example

Let’s calculate the gram formula mass of C₆H₁₂O₆ (glucose):

1. Enter C₆H₁₂O₆ in the input field.
2. Click Calculate.
3. The calculator sums the atomic masses:
   • Carbon (C): 12.011 × 6 = 72.066
   • Hydrogen (H): 1.008 × 12 = 12.096
   • Oxygen (O): 15.999 × 6 = 95.994
4. Total Gram Formula Mass: 72.066 + 12.096 + 95.994 = 180.156 g/mol

The results panel displays:

• Chemical Formula: C₆H₁₂O₆
• Gram Formula Mass: 180.156 g/mol

This makes stoichiometry and chemical calculations far easier and more accurate.
