Using the data provided, calculate the multiple bond energy (KJ/mol) of a $\mathrm{C}\equiv \mathrm{C}$bond of  ${\mathrm{C}}_2{\mathrm{H}}_2$ that energy is (take the bond energy of a C-H bond as 350 KJ/mol)

$\begin{array}{l}2{\mathrm{C}}_{\left(\mathrm{s}\right)}+{\mathrm{H}}_{2\left(\mathrm{g}\right)}⟶{\mathrm{C}}_2{\mathrm{H}}_{2\left(\mathrm{g}\right)};\mathrm{\Delta H}=225\mathrm{KJ}/\mathrm{mol}\\ 2{\mathrm{C}}_{\left(\mathrm{s}\right)}⟶2{\mathrm{C}}_{\left(\mathrm{g}\right)};\mathrm{\Delta H}=1410\mathrm{KJ}/\mathrm{Mol}\\ {\mathrm{H}}_{2\left(\mathrm{g}\right)}⟶2{\mathrm{H}}_{\left(\mathrm{g}\right)};\mathrm{\Delta H}=330\mathrm{KJ}/\mathrm{mol}\end{array}$
