A flask with a volume of 3.10 L , provided with a stopcock, contains ethane gas (C2H6) at a temperature of 310 K and atmospheric pressure 1.013×105 Pa . The molar mass of ethane is 30.1 g/mol . The system is warmed to a temperature of 381 K , with the stopcock open to the atmosphere. The stopcock is then closed, and the flask cooled to its original temperature. A) What is the final pressure of the ethane in the...
