Homework Help: Chemistry 111

Posted by Lotty on Friday, December 3, 2010 at 6:41pm.

A gas occupies a volume of 256mL at a pressure of 250torr at 32 degrees Celsius. Calculate the pressure (in atmosphere)if the volume is reduced to 156mL and the temp is increased to 62 degrees Celsius. I really need the formula that I would be using. I am confused because using PV=nRT there is no moles being given here.
I surely would appreciate it. THanks!
