Practical Examples of Gram Formula Mass Calculations
To better understand how the tool works, let’s look at a few real-world examples.
Example 1: Water (H₂O)
- Formula: H2O
- Hydrogen (H): 1.008 × 2 = 2.016
- Oxygen (O): 16.00 × 1 = 16.00
Total Molar Mass: 18.016 g/mol
This is one of the most common calculations used in basic chemistry classes.
Example 2: Carbon Dioxide (CO₂)
- Formula: CO2
- Carbon (C): 12.01 × 1 = 12.01
- Oxygen (O): 16.00 × 2 = 32.00
Total Molar Mass: 44.01 g/mol
This is widely used in environmental science and biology studies.
Example 3: Sodium Chloride (NaCl)
- Formula: NaCl
- Sodium (Na): 22.99 × 1 = 22.99
- Chlorine (Cl): 35.45 × 1 = 35.45
Total Molar Mass: 58.44 g/mol
This is commonly used in food science and laboratory experiments.
