Question Sixteen - Consider the balanced thermochemical equation... \[ 4 \mathrm{NH}_{3}(g)+5 \mathrm{O}_{2}(g) \rightarrow 4 \mathrm{NO}(g)+6 \mathrm{H}_{2} \mathrm{O}(g) \quad \Delta \mathrm{H}_{\mathrm{rxn}}=-906 \mathrm{~kJ} \] What mass (in grams) of \( \mathrm{H}_{2} \mathrm{O} \) is expected when \( 45.0 \) grams of \( \mathrm{NH}_{3} \) react completely and exactly with sufficient (excess) oxygen?
