Dinitrogen oxide (N2 O) gas was generated from the thermal decomposition of ammo-
nium nitrate and collected over water. The
wet gas occupied 123 mL at 21◦C when the atmospheric pressure was 758 Torr. What volume would the same amount of dry di-nitrogen oxide have occupied if collected at 758 Torr and 21◦C? The vapor pressure of water is18.65 Torr at 21◦C.
Answer in units of mL
