I’m giving you the reaction, but it isn’t balanced. If you know the mass of the limiting reactant, you must first use the molar mass of the reactant to convert from mass of reactant to moles of reactant. 1) for the reaction shown, find the limiting reactant and the theoretical yield in moles of potassium chloride (kcl) with the following initial quantities of reactants:
For the balanced equation shown below, if 93.8 grams of pcl5 were reacted with 20.3 grams of h2o, how many grams of h3po4 would be produced?
Any value greater than the above ratio means the top reactant is in excess to the lower number. For the first method, we�ll determine the limiting reactant by comparing the mole ratio between and in the balanced equation to the mole ratio actually present. A value less than the ratio means the top reactant is the limiting reactant. When the limiting reactant is used up.

Calculate the molecular weight of each reactant and product 3. So, to stop you from wondering how to find theoretical yield, here is the theoretical yield formula: Convert all amounts of reactants and products into moles 4. Mass of product = molecular weight of product * (moles of limiting reagent in reaction * stoichiometry of product) To find the amount of remaining excess reactant, subtract the mass of excess reactant consumed from the total mass of excess reactant given.
