How to Use This Calculator
  1. Select mode: single element lookup or compound formula.
  2. For single element: select from the periodic table list to get atomic mass.
  3. For compound: enter the formula (e.g., H2O, NaCl) to calculate total molar mass.
  4. Review molar mass in g/mol and use it to convert between grams and moles.
  5. Use for solution preparation, stoichiometry problems, and laboratory calculations.
