A rigid, sealed vessel at temperature

T

contains

5.0\times10^{22}

molecules of

\mathrm{N}_2

at a pressure of

80\,\text{kPa}

. A high-energy discharge completely dissociates all

\mathrm{N}_2

molecules into individual nitrogen atoms while the temperature remains

T

. Calculate the new pressure in the vessel.
