A Job’s Method study was carried out for the reaction:aA bB->dD fFStock solutions of A and B were prepared.[A]= 1.32 g/100mL = 100mM[B]= 100mMThese were used to prepare a series of solutions containing varying amounts of A and B but such that the total moles of A and B was held constant. The mass of product D obtained was measured solutions # solution A volume mL solution B volume mL mass product D grams1 0.3 3.2 0.122 0.4 3.1 0.163 0.5 3 0.24 0.7 2.8 0.285 0.9 2.6 0.366 1.2 2.3 0.467 1.75 1.75 0.351.) calculate the mole ration b/a?(you must include a printout of your plot and data)2.) calculate the molar mass of reactant A using the result from #1 and the given concentrations of the two solutions.
