nitrogen gas contained in a cylinder with a volume of 5.0x10^2 mL @ a temp of 30C and pressure of 710 torr. The gas is then compresse to a volume of 25mL and the temp. is reaised to 820C. what is the new pressure of the nitrogen gas??
Pf=p1*v1*t1/Tf*Vf
P=(700torr)(5.02x10^2mL)(820+273)K/(30+273)K(25mL)= 5.1x10^4 torr
please let me know if is correct and where i can find more prob. like this so i can practice.,..thankx :)

looks good to me.
A book like the Shaum's is pretty good. You may be able to find some practice problems on google. Just type in something like gas law problems.
