Agas mixture contains 30.0 mole% h2o(v) and 70.0 mole% n2. the gas temperature and absolute pressure at the start of each of the three parts of this problem are 75°c and 900.0 mm hg. ideal gas behavior may be assumed in every part of this problem. a. if some of the gas mixture is put in a cylinder and slowly cooled at constant pressure, at what temperature would the first drop of liquid form? °c b. if a 30.0 liter flask is filled with some of the gas mixture and sealed, and 70.0% of the water vapor in the flask is condensed, what volume would be occupied by the liquid water? cm3 what would be the system temperature? °c c. if the gas mixture is stored in a rigid-walled cylinder and a low-pressure weather front moves in and the barometric (atmosopheric) pressure drops from 760 mm hg to 720.0 mm of hg, what would be the new gauge pressure in the cylinder? mm hg
