A new engine is being designed that will carry 5.430 x 102 kilograms of methane, CH4, on board. How many liters of gaseous oxygen needs to be carried on board to ensure complete combustion? The oxygen will be stored at 3.500 atm of pressure and -170.84 °C. Use four significant figures in your answer. Hint: write out the balanced chemical reaction. Assume the gas behaves ideally. (If you don't know don't answer. It takes up the points I worked really hard for for people who work equally as hard to help me understand these concepts)
