Experiments on a binary solution demonstrated that the excess volume of the solution at 40°C can be expressed as V^{E}=x_{1} x_{2}\left[a_{0}+a_{1}\left(x_{1}-x_{2}\right)\right] where x, and X2 are mole fractions of both components, ao (= -2.4697 cm3 mol-1)and a (= 0.0608 cm³ mol-1) are experimental constants. Thus: a) Show that the partial molar volume of each component at 40°C is \bar{V}_{1}=V_{1}+a_{0} x_{1}^{2}+a_{1}\left(3 x_{1}-x_{2}\right) x_{2}^{2} \bar{V}_{2}=V_{2}+a_{0} x_{1}^{2}+a_{1}\left(x_{1}-3 x_{2}\right) x_{1}^{2} where V; is the molar volume of pure species i; (b) Calculate the partial molar volume for each component in a mixture containing 20%-mol of component 1.[9 marks] • Molar mass of species 1 and 2 are 70.15 g mol-1 and 89.44 g mol-1,respectively , respectively.-3Densities of pure species 1 and 2 are 0.8871 and 0.9005 g cmi
