A solution contains 59.0 g of heptane (C7H16) and 44.5 g of octane (C8H18) at 25 ∘C. The vapor pressures of pure heptane and pure octane at 25 ∘C are 45.8 torr and 10.9 torr, respectively. Assuming ideal behavior, calculate each of the following. (Note that the mole fraction of an individual gas component in an ideal gas mixture can be expressed in terms of the component's partial pressure.) The vapor pressure of heptane in the mixture. The vapor pressure...

Benzene, C6H6, and octane, C8H14, form an ideal solution. At 60°C the vapor pressure of pure benzene is 0.507 atm, and the vapor pressure of pure octane is 0.103 atm. A solution is composed of 3.53 g of benzene, and 40.2 g of octane. What is the mole fraction of benzene in the vapor phase above the liquid? In order to receive full credit, your work should clearly show the following: a) the calculation of the partial pressure of benzene...

Octane, a component of gasoline, can undergo the following combustion with an excess of oxygen gas: 2 C8H18 (ℓ) + 25 O2 (g) → 16 CO2 (g) + 18 H2O (ℓ) 10.0 mL of octane and 1.50 atm of oxygen gas are placed in a 20.0 L container at 20.0°C. Calculate the total pressure in the container after complete combustion (in atm). (Assume the vapor pressures of water and octane are negligible and temperature and volume remain constant. The density...
