A mixture of water vapor and nitrogen is admitted to a flask which contains a solid drying agent. Immediately after admission, the pressure of the flask is 760 mm Hg. After standing for a period of time, the pressure reaches a steady value of 745 mm Hg.
1. Determine the composition of the original mixture, in mole percent.
2. What is the volume of the flask? (The volume occupied by the drying agent can be assumed negligible) If the experiment is done at the 200C and the drying agent increases in weight by 0.150 g.
