Explanation / Answer

according to balanced reaction

4 x 36.5 g HCl reacts with 86.94 g MnO2

46.3 g HCl reacts with 46.3 x 86.94 / 4 x 36.5 = 27.57 g MnO2

but we have 38.7 g MnO2 so MnO2 is exess reagent

limiting reagent = HCl

4 x 36.5 g HCl gives 71 g Cl2

46.3 g HCl gives 46.3 x 71 / 4 x 36.5 = 22.51 g

therotical yield of Cl2 = 22.51 g

c) % yield = ( actual yield / therotical yield) x 100

76.7 = (actual yield / 22.51) x 100

actual yield / 22.51 = 0.767

actual yield = 17.26 g
