Problem
A mixture of N2 and water vapours is admitted to a flask which contains a solid drying agent. Immediately after admission, the pressure of the flask is 760 mm. After standing some hours, the pressure reached a steady value of 745 mm,
(1) Calculate the composition in mole % of original mixture.
(2) If the experiment is done at 20∘C and the drying agent increases in mass by 0.15 g, what is the volume of flask? (neglect volume occupied by drying agent)
