Academics

Mixture of benzene and toluene can be assumed as an ideal solution. (a) Calculate the density of a solution of benzene and toluene mixed at 1:1 weight ratio at 20 degree C and 1 atm, given that density of benzene = 0.8790 g/cm^3 and density of toluene= 0.8668 g/cm^3 at 20 degree C and 1 atm. (b) Calculate Delta mixG, Delta mixS, and Delta mixH for mixing 150.0 g of benzene with 200.0 g of toluene at 20 degree C and 1 atm.
