How to Do Stoichiometry with Wolfram|Alpha

Welcome to Quick Takes with Wolfram|Alpha. Let’s look at how to do stoichiometry. Give the name or chemical formula for each reactant and product with an arrow separating reactants from products— for example, “glucose + O2 ->H2O + CO2”. You can type the arrow using the extended keyboard or a hyphen and a greater-than sign. Then provide the amount of one or more molecules in terms of mass or the number of moles— for example, “0.1 mol glucose”. Now press “Enter”. Wolfram|Alpha will compute the answer. The first thing that Wolfram|Alpha generates is the interpretation of your query. Make sure that this is what you had in mind. Otherwise, more detail will be needed. Wolfram|Alpha generates the balanced chemical equation and does stoichiometric calculations to provide the yield, along with the amount of other reactants needed. With a Wolfram|Alpha Pro subscription, the step-by-step solution is provided in addition to the answer. The steps can be studied one by one or all at once. If the initial amounts of two or more reactants are provided— for example, “0.1 mol glucose + 10 g O2 ->H2O + CO2″— Wolfram|Alpha identifies the limiting reagents in addition to providing the yield and the amounts of other reactants necessary. Additionally, if the amount of any product is given— for example, “0.1 mol glucose + 10 g O2 ->5 g H2O + CO2″— Wolfram|Alpha computes the yield percent too.
