A flask with a volume of 1.00 LL , provided with a
stopcock, contains ethane gas (C2H6)(C2H6) at a
temperature of 282 KK and atmospheric pressure
1.013×105 PaPa . The molar mass of ethane is
30.1 g/molg/mol . The system is warmed to a temperature
of 373 KK , with the stopcock open to the atmosphere. The
stopcock is then closed, and the flask cooled to its original
temperature.
What is the final pressure of the ethane in the flask?
