Stoichiometry 與 Pocket Chemist 使用情況與統計
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.

Pocket Chemist is the perfect tool to help high school and first year college chemistry students learn core concepts in chemistry. It is like having a chemist in your pocket. This app gives you access to a Periodic Table with grouping options and information about each element like chemical and physical properties and isotope abundance.
Chemical nomenclature can be tricky, but with Pocket Chemist you can enter your chemical name or formula and learn its molar mass, bonding type, oxidation states, percent composition, and solubility in water. It couldn’t be easier!
When it is time to determine molecular composition simply enter elements with molecular mass or percent composition and determine empirical or molecular formulas.
Stoichiometry is hard to say, but easy to calculate. Balance equations in a snap and learn the reaction type, like synthesis, decomposition, single replacement, double displacement (or metathesis), and combustion! Calculate the amount of product formed from the reaction or the amount of reactants needed based on your products. Pocket Chemist even shows the limiting reagent. Select units like volume @STP, moles, grams, and molarity for quick and easy conversions.
New to this release is the Gas Laws calculator. Enter pressure, volume, moles, and/or temperature and automatically calculate results using Ideal, Combined, Boyles, Charles, or Gay-Lussac gas laws.
Pocket Chemist is the chemistry homework helper you have been looking for!
