One type of gas mixture used in anesthesiology is a 50% / 50% mixture (by volume) of nitrous oxide (N2O) and oxygen (O2), which can be premixed and kept in a cylinder for later use. Because these two gases don't react chemically at or below 2000 psi, at typical room temperatures they form a homogeneous single gas phase, which can be considered an ideal gas. If the temperature drops below -6°C, however, N2O may begin to condense out of the gas phase. Then any gas removed from the cylinder will initially be nearly pure O2; as the cylinder empties, the proportion of O2 will decrease until the gas coming from the cylinder is nearly pure N2O. In a test of the effects of low temperatures on the gas mixture, a cylinder filled at 25.0°C to 2000 psi (gauge pressure) is cooled slowly and the pressure is monitored.1. What is the expected pressure at -5.00∘C if the gas remains a homogeneous mixture?

Expert Answer

Step 1

From Dolton’s law, total Pressure= Pn + Po; where Pn and Po are pressures from N2O and O2 respectively.

Step 2

Since the volume of 2 gases mixed is equal, P1=P2
