Asolution is prepared by mixing 25 ml of pentane (c5h12; density = 0.63 g/cm3) with 125 ml of benzene (c6h6; density = 0.0867 g/cm3). assuming vector volumes and upon mixing determine the mole fraction and molarity of pentene in the solution

The density of the solid phase of a substance is 0.90 g/cm3 and the density of the liquid phase is 1.0 g/cm3. a large increase in pressure will a. lower the freezing point b. raise the freezing point c. lower the boiling point d. raise the triple point e. lower the triple point
