Use the equation pV = nRT
To solve for temperature:
T =(pV)/(nR)
Be consistent with the units.
Convert the unit Torr to Pascal or Newton per sq.meter.
Torr is a unit of pressure equal to about 133.3 pascals or one millimeter of mercury supported in a column
Convert 240 ml to cubic meter
1ml =1 cubic cm
1 li = 0.001 cubic meter
You can use the appropriate value of the Universal Gas Constant R. R = 8.3145 J/mol K
T =(pV)/(nR)
= [(729 torr X 133.3 Pa/torr) (0.24li X.001cubic meter/li)] / [3.33 (exp -3)mol ( 8.3145 J/mol K)]
T = 842.3 K

Wyatt, how about learning some spelling and grammar? What you want is the Temperature. How you get it? Ta, ta PV=nRT. You have P, you have V, you have n, and you should be able to select the correct R for the units you use. So then you caclucate T.
