Butane undergoes combustion while it reacts with oxygen to produce carbon dioxide and water. Utilizing the ideal gas law equation, compute the volume in liters of oxygen required to burn all the butane at 0.850atm and 25 degrees Celsius if a tank contains 55.2 g of butane.2C4H10 (g) + 13O2 (g) ---> 8CO2 (g) + 10H2O (g)
