2 A 10.5 mL sample of liquid ethanol (C,H,OH, density = 0.789 g/mL) was injected into a 10.0 L cylinder containing O, at a pressure of 4.50 atm and a temperature of 25 °C. The cylinder was heated to 125 °C and a spark was used to ignite the ethanol, which was completely combusted. What was the final total pressure in the cylinder (in atm) after the reaction, while it was still at 125 °C?
