An atom has two energy levels with energy difference 2.2 eV between them. A gas of these atoms has \(8 \times 10^{20}\) atoms in the upper state and \(5 \times 10^{20}\) atoms in the lower state. Ignoring spontaneous emission, the maximum possible energy released by this gas of atoms by stimulated emission is \(E\) Joules. The value of \(E\) (rounded off to one decimal place) is ______ \((e = 1.6\times10^{-19}\text{ C})\)
