Enter any chemical formula — from a single element to a complex organic compound — and instantly get its exact molar mass in g/mol, along with the atomic breakdown of every element involved.
The weight calculator takes a chemical formula as text and calculates its molar mass by summing the atomic mass of each element times its subscript, correctly handling parentheses and hydrates.
Weight of a single element, taken directly from the built-in periodic table.
Weighted sum of every atom in the formula, with support for parentheses, subscripts, and hydrates (·nH2O).
Shows what percentage of the total mass each element in the formula contributes.
