Practical Examples of Molecular Mass Calculation
Here are some real-world examples to understand how the calculator works:
Example 1: Water (H2O)
- Hydrogen (H): 1.008 × 2 = 2.016
- Oxygen (O): 16.00 × 1 = 16.00
Molecular Mass = 18.016 u
👉 This is widely used in biology, environmental science, and chemistry experiments.
Example 2: Carbon Dioxide (CO2)
- Carbon (C): 12.01 × 1 = 12.01
- Oxygen (O): 16.00 × 2 = 32.00
Molecular Mass = 44.01 u
👉 Important in studying respiration, climate change, and industrial gas reactions.
Example 3: Sodium Chloride (NaCl)
- Sodium (Na): 22.99 × 1 = 22.99
- Chlorine (Cl): 35.45 × 1 = 35.45
Molecular Mass = 58.44 u
👉 Commonly used in food science and medical saline solutions.
