Two vessels containing gases are separated by a stopcock. The first holds 2.0 L of nitrogen at 1.0 atm and 25°C; the second contains 3.0 L of oxygen at 2.0 atm and 25°C. (a) When the stopcock is opened, how does the volume of N, change? What is the partial pressure of N, after mixing? (b) How does the volume of O, gas change after mixing? What is the partial pressure of O, in the mixture? (c) What is the total pressure of gas in the mixture?​
