Passage Problem 15.87: Anesthetic gases. One type of gas mixture used in anesthesiology is a 50%/50% mbture (by volume) of nitrous oxide (N2O) and oxygen (02 ), 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 02. As the cylinder empties, the proportion of O2 will decrease until the gas coming from the cylinder is nearly pure Part A In a hospita pure oxygen may be delivered at volume at 20 °C? 9 psi gauge pressure and then mixed with N20 What olume o' oxygen at 20 C and 50 psi gauge pressure should be mixed with 1.7 kg o, N20 to get a 50%/50% mixture by Express your answer in cubic meters to two significant figures.
