Pentane (C5H12) and heptane (C7H16) are two hydrocarbon liquids present in gasoline. At 20.0 clesuis, the vapor pressue of pentane is 422 torr and the vapor pressue of heptane is 36.0 torr. What will be the total vapor pressure (in torr) of a sloution prepared by mixing equal masses of the two liquids? To solve for the vapor pressure of the solution, the mole fraction of each component is necessary, but first the moles of each component must be calculated. Calculate the moles of both pentane and heptane. (Hint : Assume 50.0 g of each component .)
