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 resources

The Common App... An experiment was conducted using KNO3. The table below shows the data obtained after dissolving different masses of KNO3 in 10 ml of deionized water and then cooling to determine the temperature at which the different concentration of salts begin to recrystallize Concentration of KNO3 Saturation temperature(°C) 2g/10 ml 52.5 4g/10 ml 54.7 6g/10 ml 66.7 8g/10 ml 80.2 If a student dissolve 24g of KNO3 in 120 ml of deionized, at what temperature do you expect to see recrystallization O 52.5 degree celsius O 66.7 degree celsius 0:54.7degrce celsius O100.2 degree celsius
