Next, using your calculated values for the number of moles, n, the corrected pressure, Pcorr, of H2, and the ideal gas equation, PV = nRT, determine the volume of the pressure vessel (in liters) and enter below. Note 1. Assume that the final system temperature is 22 °C.
Note 2. Remember to convert P and T to units that correspond to those used in the gas constant, R.
