About the Stoichiometry Calculator
A balanced-equation coefficient ratio can relate an entered amount in moles to a target amount.
Formula
Target moles = given moles × target coefficient ÷ given coefficient.
Example
With 2 given moles, coefficient 2 and target coefficient 1, the calculated target amount is 1 mole.
