Baking soda; it reacts with vinegar in the classic volcano experiment.
Step-by-step calculation
Add up the atomic masses of every atom in the formula:
1 × 22.99 + 1 × 1.008 + 1 × 12.011 + 3 × 15.999 = 84.01 g/mol
| Element | Atoms | Atomic mass (u) | Subtotal (g/mol) | % by mass |
|---|---|---|---|---|
| Sodium (Na) | 1 | 22.99 | 22.990 | 27.37% |
| Hydrogen (H) | 1 | 1.008 | 1.008 | 1.20% |
| Carbon (C) | 1 | 12.011 | 12.011 | 14.30% |
| Oxygen (O) | 3 | 15.999 | 47.997 | 57.14% |
