Question

A flexible container holds a volume of 2.34 L of carbon dioxide at pressure and temperature of 652 mm Hg 
and 22.0°C. If the pressure changes to 1.5 atm and the volume becomes 1340 mL, what is the new
temperature of the carbon dioxide gas?

Jim · Answer

PV=nRT <<<memorize!!
n is moles, R is gas constant (use correct one!), T is temp in K (C+273.15)
Since you have a before and after with the same n &R simplifies to
PV/T initial  = PV/T final
1 atm = 760 mmHg
Now sub in your numbers and solve, round answer to 3 sigfigs
