The method is modified for finding integer coefficients. Our stoichiometry calculator uses the Gauss-Jordan elimination algorithm for solving a set of linear equations. But in case of complex reactions involving many compounds, it is preferable to balance equations using algebraic methods, based on solving a set of linear equations. There are a number of methods for balancing chemical equations. In case of ionic reactions, the same electric charge must be present on both sides of the equation. Thus, each side of the equation must represent the same quantity of atoms of any chemical element. It’s important because in a chemical reaction, the quantity of each element does not change (the law of conservation of mass). This means looking for stoichiometric coefficients for the reactants and products. So, the first step in stoichiometry calculations is balancing chemical equations. Knowing the molecular weight of the compounds involved in the reaction, it is easy to find the mass of these compounds in grams. For any balanced chemical equation, whole numbers (stoichiometric coefficients) are used to show the amounts (in moles) of both the reactants and products. Stoichiometry is the field of chemistry that studies the relative amounts of reactants and products in chemical reactions. You can enter either the required number of moles or weight in grams for one of the compounds in the corresponding field, and then press the ‘Enter’ key, to compute new values for the rest of the compounds. The reaction stoichiometry is calculated automatically for a balanced equation, with the number of moles for the compounds being the same as the stoichiometric coefficients. In what follows is a more detailed syntax guide to our calculator.

You can enter a chemical equation manually or paste the equation copied from a web page or text document (including DOC or PDF file). In case the original equation was unbalanced, the field with this equation is highlighted in light pink.

The equations may include free electrons and electrically charged molecules (ions) as well as hydrated compounds. By converting grams to atoms, you can study the properties and behaviors of substances at the atomic level and better understand the fundamental nature of matter.This online Stoichiometry Calculator finds the stoichiometric coefficients to balance a given chemical equation and computes amounts of the reactants and products of the reaction, both in moles and grams. This formula is useful in many fields, including chemistry, materials science, and physics. The final result is the number of atoms in the given number of grams.Divide the result from step 3 by the atomic mass: atoms = (grams * N) / Atomic Mass.Multiply the number of grams by Avogadro’s number: grams * N = atoms.This is the value that you want to convert to atoms.
Determine the number of grams you have.This value is usually expressed in grams per mole (g/mol) and can be found in the periodic table. Determine the atomic mass of the element you want to convert to atoms.Here is the step-by-step process to convert grams to atoms: Where Avogadro’s number (N) is the number of atoms in one mole of a substance and is approximately 6.02214076 * 10^23 atoms per mole. To convert grams to atoms, we need to use the formula below:Ītoms = (grams * Avogadro’s number) / Atomic Mass
