HBr   + NaOH = NaBr   + H2O

first in this reaction we have to find moles of both reactents and limiting reagent

now moles of HBr = 79.3/80

                          = 0.991

moles of NaOH = 52.9/40

                        = 1.32 mole

now limiting reagent in this reaction is HBr

theartical yield = M.Wt of Product x limiting reagent weight/limiting reagent M.Wt

                          = 18 x 79.3/80

                          = 17.84 gm
