The study of the quantitative relationships between the amounts of reactants used and the amounts of products formed by a chemical reaction is called stoichiometry.
The coefficients in a chemical equation represent not only the number of individual particles but also the number of moles of particles.
The mass of each reactant and product is related to its coefficient in the balanced chemical equation for the reaction by its molar mass.
What is the mole ratio of methanol: oxygen gas: carbon dioxide: water in the equation above?
2: 3: 2: 4
A ______ ______ is a ratio between the numbers of moles of any two substances in a balanced chemical equation.
