This Instructable is good for people who are just learning stoichiometry and those who want an easier way. This is also great for all those people who like to use chemical reactions to blow stuff up. You can find the right amount to optimize the reaction and save reactants so you don't...

Stoichiometry can be used to find the mass of a substance in a chemical reaction when the amount of another substance is known. Using mole ratios from a balanced equation and the molar mass of the substances involved, these calculations can be performed when given the number of moles of a ...

While stoichiometry mainly refers to mass, expect to convert between other units, such as the mole and volume units. Stoichiometry Definition Stoichiometry is the study of the quantitative relationships or ratios between two or more substances undergoing aphysical changeorchemical change(chemicalreaction)...

So, the concept of a mole is similar to the concept of a dozen. If we have one dozen eggs and one dozen elephants, we are saying we have 12 eggs and 12 elephants. But obviously, a dozen eggs weigh far less than a dozen elephants. It is the same with molar units. For example, ...

Stoichiometry is the study of patterns of mass balance in the chemical conversions of different types of matter [3]. Many people are introduced to, and use, stoichiometry when balancing chemical reactions in introductory chemistry classes. These principles of mass balance are also widely used by ec...
