a synthesis gas of the following composition$4\mathrm{.}5\%$ co$,26\mathrm{.}0\%$ co$,13\mathrm{.}0\%$ h$,0\mathrm{.}5\%$ chy$,$ and $56\mathrm{.}0\%$ n;$,4$s burned with $10\%$ excess air. the barometer reads $98$ kpa. calculate the dew point of the stack gas. to prevent condensation and consequent corrosion, stack gases must be kept well above their dew point.

Please dont use gpt$,$ its a chemichal engineer question
