Chapter 10, Problem 110RQ

*10.110 A mixture was prepared in a 0.500 L reaction vessel from 0.300 L of ${\text{O}}_{\text{2}}$

(measured at $\text{25 °C}$ and 74.0 cm Hg) and 0.400 L of ${\text{H}}_{\text{2}}$

(measured at $\text{45 °C}$ and 1250 torr). The mixture was ignited and the ${\text{H}}_{\text{2}}$ and ${\text{O}}_{\text{2}}$ reacted to form water. What was the final pressure inside the reaction vessel after the reaction was over if the temperature was held at $\text{122 °C}$?
