Molecular Mass Calculator

Calculates the molecular mass (molar mass) of a chemical formula as you type it.

Features

• Real-time calculation — results update on every keystroke
• Parentheses support — handles nested groups like Mg(OH)2 and Fe2(SO4)3
• Detailed breakdown — shows each element, its atomic mass, count, and contribution to the total
• Atomic mass reference — values sourced from IUPAC, displayed per element

Usage

Type a chemical formula into the input field. Examples:

Formula	Mass
H2O	18.0152
Mg(OH)2	58.3196
Ca(NO3)2	164.0878
Fe2(SO4)3	399.8778
C6H12O6	180.1554
