Diethyl ether, c4h10o was a widely used anesthetic in the early days of surgery. it has a vapor pressure of 537 torr at 25 oc. a 10.00 ml sample (d = 0.708 g/ml) is placed in a sealed 0.205 l flask. what is the maximum volume in liters the flask can have if equilibrium is to be maintained between liquid and vapor?

Butane gas reacts with oxygen gas to give carbon dioxide gas and water vapor (gas). if you mix butane and oxygen in the correct stoichiometric ratio, and if the total pressure of the mixture is 390 mmhg, what is the pressure (in mmhg) of water vapor after the reaction is completed (temperature and volume do not change).
