Mole Ratios

Learning how to complete mole to mole stoichiometry problems is a balancing act. The coefficients of a balanced equation provide information about the relative amounts of products and reactants in a reaction. The coefficients are the numbers in front of chemical formulas in an equation. They represent the number of moles of each substance. They can also represent the number of molecules of each substance. The coefficients are used to balance an equation, making sure that the mole ratio on the right side of the equation is equal to the mole ration of the right side of the equation. By doing so, the equation adheres to the Law of Conservation of Matter.
