Amixture of nitrogen and water vapor is admitted to a flask whichcontains a solid drying agent. Immediately after admission, thepressure of the flask is 760 mm Hg. After standing for a period oftime, the pressure reaches a steady value of 745 mm Hg. (a)Calculate the composition of the original mixture, in mole percent.(b) If the experiment is done at 200C and the dryingagent increases in weight by 0.150 g, what is the volume of theflask? (The volume occupied by the drying agent can be assumednegligible)
