Introduction
Enter a chemical formula like H2O, Ca(OH)2, or C6H12O6 to get molar mass, elemental composition, and stoichiometry conversions.
Step-by-step
- Enter a chemical formula
- Review molar mass and composition
- Convert mass ↔ moles ↔ molecules
Worked example
H2O has molar mass 18.015 g/mol; 36.03 g equals 2 mol or ~1.204×10²⁴ molecules.
Use cases
- Calculate reagent masses for lab preparations
- Convert between grams, moles, and molecule count
- Verify formula weights for homework or QC
