Stoichiometry

What is stoichiometry?

Stoichiometry is the branch of chemistry that involves the calculation of reactants and products in chemical reactions.

What is a mole?

A mole is a unit of measurement used in chemistry to express amounts of a chemical substance, equivalent to 6.022 x 10^23 particles.

What is the law of conservation of mass?

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction.

What are reactants?

Reactants are the starting substances in a chemical reaction that undergo transformation.

What are products?

Products are the substances formed as a result of a chemical reaction.

What is a balanced chemical equation?

A balanced chemical equation has equal numbers of atoms of each element on both sides of the equation.

What does the coefficient in a chemical equation represent?

The coefficient indicates the number of moles of each substance involved in the reaction.

What is molar mass?

Molar mass is the mass of one mole of a substance, usually expressed in grams per mole (g/mol).

What is a stoichiometric ratio?

A stoichiometric ratio is the ratio of the coefficients of reactants and products in a balanced chemical reaction.

How do you convert grams to moles?

To convert grams to moles, divide the mass of the substance in grams by its molar mass.
