You are told that 35.5 mL of xenon exerts pressure of .255 atm at -45. A) What volume does the sample occupy at 1 atm. and 298 K? B) What pressure would it exert if it were transferred to a flask of volume 12 mL at 20 C? C) calculate the temperature needed for the xenon to exert a pressure of 5.00 x 10^2 Torr in the flask.
