Stoichiometry Calculator
Convert from a known reactant or product amount to a target substance using a balanced chemical equation.
What This Tool Does
Convert from a known reactant or product amount to a target substance using a balanced chemical equation.
known amount → moles → mole ratio → target moles → target grams
Worked Example
With 4.00 g H2 in 2 H2 + O2 -> 2 H2O, the theoretical water produced is about 35.7 g.
Common Mistakes
Choose substances exactly as they appear in the equation, and avoid mixing grams and moles without converting.
