Assuming that the reaction will go to completion we can predict this amount of product from the stoichiometric coefficients of the balanced chemical equation. Be sure that actual and theoretical yields are both in the same units so that units cancel in the calculation. The reaction formula gives the whole number of moles needed to complete and balance the reaction. Express mass of the reactants in terms of moles.
