A mixture of propane and oxygen in a 1L closed vessel has an internal pressure A mixture of propane and oxygen in a 1L closed vessel has an internal pressure of 4atm. at 373K. When the mixture is ignited, the reaction produces CO2(g) and of 4atm. at 373K. When the mixture is ignited, the reaction produces CO2(g) and H2O(g) until all the oxygen is consumed. After the reaction, the pressure of the H2O(g) until all the oxygen is consumed. After the reaction, the pressure of the vessel is 4.2atm at the same temperature. Calculate the weight of the oxygen vessel is 4.2atm at the same temperature. C
