Elemental Mass Breakdown & Percent Composition
| Element | Symbol | Atoms | Atomic Wt. | Total Mass | Mass % |
|---|---|---|---|---|---|
| Oxygen | O | 6 | 15.999 | 95.9940 g/mol | 53.28% |
| Carbon | C | 6 | 12.011 | 72.0660 g/mol | 40.00% |
| Hydrogen | H | 12 | 1.008 | 12.0960 g/mol | 6.71% |
How It Works
The calculator parses chemical symbols, brackets, multipliers, and hydrate dots according to IUPAC standard atomic weights to sum the total molar mass.
