How many grams of NaCl are produced when 80.0g of O2 are produced in the following reaction?

The correct answer to this question is A, 576.00g oxygen b. 97.4g NaCl. This question would be found on a chemistry test, focused on stoichiometry. This subset of chemistry is the calculation of the products and reactants in chemical reactions. Stoichiometry was first used by Jeremias Benjamin Richter in 1792.

The term derives from Greek terms. Stoichiometry can also be used to covert grams to moles by using molar mass. It is also important to understanding the law of definite proportions and the law of conservation of mass. Stoichiometry can find the amount of a product yielded by a reaction.
