Given reaction- C6H6 + Br2 → C6H5Br + HBr Calculating moles of bromobenzene that can be produced form benzene and bromine. 0.38 mole C6H6 x 1 mole C6H5Br1 mole C6H6=0.38 moles C6H5Br0.38 mole Br2 x 1 mole C6H5Br1 mole Br2 = 0.38 moles C6H5Br Answer- 0.38 moles When reactants are in stoichiometric amounts, it is difficult to determine the limiting reagent. In such cases, there is enough of excess reagent and all reactants gets completely consumed. However, it is not possible for any chemical reaction to not have an limiting reagent. % yield = Actual yieldTheoretical yield x 100 % yield = 0.19 moles C6H5Br 0.38 moles C6H5Br x 100 % yield = 50.0 %
