Chemistry is just cooking with atoms. The Stoichiometry Calculator helps you convert Grams to Moles to Moles to Grams, predicting exactly how much product a reaction will create.
Stoichiometry is the hardest part of Gen Chem because it involves multiple conversion steps. This tool automates the 'Dimensional Analysis' chain, preventing calculation errors.
Grams → Moles → Moles → Grams workflow
Calculates Limiting Reactant
Calculates Theoretical Yield
Simple step-by-step logic
Mass is conserved. You can't create relationships between grams directly—you must go through the 'Mole Bridge'. Moles are the universal currency of chemistry.
