3. Two flasks are connected by a stopcock as shown below. The 5.0 L flask contains CH4 at a pressure of 3.0 atm, and the 1.0 L flask contains C2H6 at a pressure of 0.55 atm.
(a) Calculate the total pressure of the system after the stopcock is opened. Assume that the temperature remains constant.
(b) Calculate the pressure of the initial sample of methane using the Vander Waals equation.
(c) Calculate the rate of diffusion between the two gases.
4. Octane, C8H18(l), has a density of 0.703 g/mL at 20°C. A 255 mL sample of C8H18(l), measured at 20°C reacts completely with excess oxygen as represented by the equation below.
2 C8H18(l) + 25 O2{g) à 16 CO2(g) + 18 H2O(g)
