The value of \(\Delta E\) for combustion of \(32 \mathrm{~g}\) of \(\mathrm{CH}_4\) is \(-1770778 \mathrm{~J}\) at \(298 \mathrm{~K}\). The \(\Delta H\) combustion for \(\mathrm{CH}_4\) in \(\mathrm{J} \mathrm{~mol}^{-1}\) at this temperature will be (Given that, \(R=8.314 \mathrm{~JK}^{-1} \mathrm{~mol}^{-1}\) )
