How to Use the Calculator
- Enter the chemical formula of the substance in the input field. For example, "H₂O" for water, "CO₂" for carbon dioxide, or "NaCl" for sodium chloride.
- Click the "Calculate" button to compute the molar mass.
- The calculator will display the total molar mass in g/mol and break down the calculation by element.
Understanding Molar Mass
Molar mass is the mass of one mole of a substance. It is expressed in grams per mole (g/mol) and is calculated by summing the atomic masses of all atoms in the molecular formula.
Example Calculations
- Water (H₂O): 2 × (1.008 g/mol) + 1 × (15.999 g/mol) = 18.015 g/mol
- Carbon Dioxide (CO₂): 1 × (12.011 g/mol) + 2 × (15.999 g/mol) = 44.01 g/mol
- Sodium Chloride (NaCl): 1 × (22.990 g/mol) + 1 × (35.453 g/mol) = 58.44 g/mol
