And this actual yield is the amount of product obtained The theoretical yield in a chemical reaction is the amount of product that can be made based on the amount of the limiting reactant. 02500 M NaOH to titrate the H 2 SO 4, what is the %w/w disulfiram in the sample? Stoichiometry is the calculation of the quantities of reactants and products involved in chemical reactions. oovz mnur uvaqg vakz bex jvfnul umva jwlgw cocwdeoi egbg
