Chapter 14, Problem 101IAE

At $20°\text{C}$ , liquid benzene has a density of $0.879{\text{g/cm}}^2$ ; liquid toluene, $0.{\text{867g/cm}}^{\text{2}}$ . Assume ideal solutions.

1. Calculate the densities of solutions containing 20,40,60, and 80 volume percent berzene.
2. Plot a graph of density versus volume percent composition.

Write an equation that relates the density (d) to the volume percent benzene (V) in benzene-toluene solutions at $20°\text{C}$ .
