A sample of helium gas initially at 37.0 degrees C, 785 torr and 2.00 L was heated to 58.0 degrees C while the volume expanded to 3.24 L. What is the final pressure in atm?
a)1.79
b)3.21
c)0.681
d).517
e)none of the above
please explainI need to know how to do thisthis is a practice problemI don't understand.

d) should read 517, not .517

Use (P1V1)/T1 = (P2V2)/T2
