A sample of oxygen is collected over water at 22°C and 752 mm Hg in a 125-mL flask. The vapor pressure of water at 22°C is 19.8 mm Hg.
(a) What is the partial pressure of oxygen?
(b) How many moles of dry gas are collected?
(c) How many moles of wet gas are in the flask?
(d) If 0.0250 g of N2(g) are added to the flask at the same temperature, what is the partial pressure of nitrogen in the flask?
(e) What is the total pressure in the flask after nitrogen is added?
