following the general experimental procedure of experiment 34a, 87 microliters of acetophenone (120.15 g/mol, 1.03 g/ml) was reacted with 3.1 ml of aqueous naocl (5% available chlorine) to give 71 mg of benzoic acid (122.12 g/mol) as a white solid. what is the percent yield of product? enter your answer as digits only (no percent or %), using the proper number of significant figures.



Answer :

The percent yield of the product = 64.88 %

one mole of acetophenone  equals to one mole of benzoic acid

therefore ,

number of  mole of acetophenone = number of mole of benzoic acid

number of moles of acetophenone = mass / molar mass

                                                           = 1.03 × 87 × 10⁻⁶ moles

                                                           = 89.61 × 10⁻⁶ moles

now tactual yield :

number of moles of benzoic acid  = mass / molar mass

                                                        = 0.071 / 122.12

                                                        = 58.14 × 10⁻⁶ moles

the percent yield = (actual yield / theoretical yield ) × 100 %          

                            =    (58.14 × 10⁻⁶ / 89.61 × 10⁻⁶)  × 100 %        

                            = 64.88 %

Thus, The percent yield of the product = 64.88 %
