モーラー質量計算機
Molar Mass Calculator Type a chemical formula and get the exact molar mass in g/mol, a per-element breakdown, and the mass percentage of each element. Atomic weights use IUPAC 2021 standard values so results are reliable for laboratory and coursework use. Parentheses, polyatomic groups, and hydrate notation (CuSO4·5H2O) are fully supported. How to Use Enter a chemical formula in the input box (for example, C6H12O6 for glucose). Pick an output unit: g/mol, kg/mol, or atomic mass units per molecule. Set the number of decimal places (4 is standard for lab work). Read the total molar mass from the summary card and review each element’s contribution and mass percentage in the ...
