Perfect for classroom assignments, laboratory preparations, and chemical research, this tool eliminates the need for periodic table lookups and manual calculations. Accessible on any device and completely free to use, our Molecular Weight Calculator is your fast and reliable companion for chemical analysis.

Frequently Asked Questions (FAQ)

Q: What is molecular weight?
Molecular weight (or molar mass) is the total mass of all atoms in a molecule, typically expressed in grams per mole (g/mol).

Q: How does the calculator work?
It parses the chemical formula you enter and adds up the atomic weights of each element based on standard values from the periodic table.

Q: Can I use it for complex compounds?
Yes! It supports multi-element compounds, parentheses, and multiple atoms (e.g., Ca(OH)₂, Na₂SO₄).

Q: Is this tool accurate?
Absolutely. It uses precise atomic weights to ensure reliable molar mass calculations.
