Stoichiometry vs DrPhos' Chemistry Pro

Stoichiometry is an ultimate tool for balancing chemical reactions, finding molar masses, moles and actual masses of reactants and products based on their chemical formulas, stoichiometric coefficients and any quantitative data provided, that available on Apple Store for iOS and Mac . It is enough to provide initial or final (after reaction accomplishment) mass or moles of one of the reaction component, to calculate all required and obtained masses and moles of all components. If data is available for several components, then limiting reagent will be found based on reaction stoichiometry. Molecular formula format: charge or unpaired electrons (in free radicals), if exist, must be provided as well, separated by coma: Na,+ ; R,: ; SO4,2- . Application supports state indexes: (g), (s), (l), (aq) – all are lowercase only, placed at the end of compound formula. App can send the data to  Gas Phase Stoichiometry app to further calculate pressures and volumes of gaseous compounds. Either moles or masses can be filled in, but if by mistake both are provided and they don’t match, then the moles value will have a preference. Component will be taken into consideration once the stoichiometric coefficient is provided for it. For balancing redox reactions please refer to Electrochemistry application.
