- Question 5.d of 11 Submit Most anesthetic 'gases' are volatile liquids and therefore must be vaporized in order to be delivered in a gas form to the lungs. The vaporizer holds the gas in an equilibrium condition in which the concentration of the gas molecules remains constant on average. Oxygen gas then flows into the vaporizer and moves a mixture of O, and anesthesia into the tube for the patient. | %v/v 1 2 3 4 5 C 7 8 +/- x 10 0 Tap here or pull up for additional resourcesPrepare 0.1 M solutions of NaOH and 0.1 M ethyl acetate using high-purity distilled water.
