1. What is Molar Mass?

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). It's calculated by summing the atomic masses of all atoms in a chemical formula.

2. How the Calculator Works

The calculator uses the formula:

Where:

• Atomic Mass — The mass of a single atom of each element (from periodic table)
• Count — The number of atoms of each element in the formula

Example: For H₂O, the calculation is (1.008 × 2) + 15.999 = 18.015 g/mol

3. Importance of Molar Mass

Details: Molar mass is essential for converting between grams and moles, preparing solutions, stoichiometric calculations, and determining empirical/molecular formulas.

4. Using the Calculator

Tips: Enter the chemical formula using standard notation (e.g., H2O, C6H12O6). The calculator recognizes element symbols and subscripts.

5. Frequently Asked Questions (FAQ)

Q1: What if my element isn't recognized?
A: This calculator includes common elements. For comprehensive calculations, use a full periodic table database.

Q2: How are parentheses handled in formulas?
A: This version doesn't support parentheses or complex formulas like (NH4)2SO4.

Q3: Why are my results slightly different from other calculators?
A: Different sources may use slightly different atomic mass values due to variations in isotopic abundance.

Q4: Can I use this for ionic compounds?
A: Yes, as long as you enter the correct formula (e.g., NaCl for sodium chloride).

Q5: How accurate are these calculations?
A: Results are accurate to 3 decimal places using standard atomic weights.
