A student measured 15.292g of fumaric acid, dissolved it in 50 mL of ethanol, added 0.039g of ruthenium catalyst, and carefully transferred the resulting mixture into a 200mL "bomb". After the vessel was pressurized with hydrogen gas and heated to 80 degrees C, the monometer showed the initial pressure inside the "bomb" to be 77.2 atm. Assuming 100% yield, calculate the pressure that should be inside the "bomb" when the reaction is over.
