Please have patience reading this long post. A closed vessel with rigid walls contains 1 mol of 238 U 92 and 1 mol of air at 298K. Considering complete decay of 238 U 92 to 206 Pb 82, the ratio of the final pressure to the initial pressure of the system at 298 K is? Although the ans given by IIT is 9, but they have not taken into account the pressure exerted by the air present in the vessel. After taking this into account, the ans should be 5 Please explain
