A 5.80-g sample of lead nitrate, Pb(NO3)2, molar mass = 331 g/mol, is heated in an evacuated cylinder with volume of 3.25 L. The salt decomposes when heated,  according to the equation:  2Pb(NO3)2(s) => 2PbO(s) + 4NO2 (g) + O2 (g) Assuming complete decomposition, what is the cylinder after decomposition and cooling to a temperature of 250 K? Assume PbO(s) takes a negligible volume.  Enter answer without a unit.
