WebCalculation of reacting masses and volumes of substances, including examples in which some reactants are in excess. In some chemical reactions it may be that one or more of … WebWhen performing reacting mass calculations, the limiting reagent is always the number that should be used, as it indicates the maximum possible amount of product that can form. Once all of a limiting reagent has been used up, the reaction cannot continue. The steps are: Convert the mass of each reactant into moles by dividing by the molar masses.
WebA theoretical yield is the maximum possible mass of a product that can be made in a chemical reaction. It can be calculated using: the balanced equation the mass and relative formula mass... WebReacting masses. The masses of reactants are useful to determine how much of the reactants exactly react with each other to prevent waste. This equation shows the ratio …
