Just like all the other questions you've posed, this can be answered using P1V1/T1 = P2V2/T2.  Just remember to change all temperatures to K by adding 273 to degrees C.

Sure.  If it has units of degrees C or degrees K, it is the TEMPERATURE (the temperature should be in Kelvin)
If it has units of atmospheres, mm Hg, kPa, etc. it is PRESSURE
If it has units of liters, milliliters, etc., it is VOLUME (the volume should be in liters)
 
So, in this problem 
-100 degrees celcius is TEMPERATURE but must be changed to Kelvin by adding 273 to get 173 degrees K
7.5 liters is VOLUME
506.5 kPa (not kps) is PRESSURE
1215.6 kPa is PRESSURE
50 degrees celsius is TEMPERATURE and converst to 273 + 50 = 323 degrees K
 
Does this help answer your question?

No.  I don't think so.
(506.5)(7.5)/173 = (1215.6)(V2)/323
V2 = 5.83 L
