Reads standard chemical notation: elements, integer subscripts, and nested ( ) or [ ] groups.

Molar mass is the sum of (count × atomic weight) for every element in the parsed formula.

Each row shows how much of the total formula mass comes from that element—useful for percent composition problems.

Try C6H12O6, CaCO3, or H2SO4 and compare to your textbook’s listed atomic weights.

After finding g/mol here, use moles-to-grams or molarity calculators for solution stoichiometry.

No isotopic masses, dot hydrates, or fractional subscripts—keep formulas in simple integer form.
