Question 14 of 25 A certain mass of nitrogen gas occupies a volume of 4.44 L at a pressure of 5.80 atm. At what pressure will the volume of this sample be 6.82 L? Assume constant temperature and ideal behavior.

Since you’re working with pressures and volumes, you need to use the gas law that relates the two. This would be Boyle’s law (P1V1 = P2T2). If we say that P1 is 5.80 atm and V1 is 4.44 L (notice that we kept those numbers together), and that V2 is 6.82 L, then P2 is what we’re looking for. Substituting these in:

P1V1 = P2V2
(5.80 atm)(4.44 L) = P2(6.82 L)
P2 = 3.78 atm

The sample will have a volume of 6.82 L at a pressure of 3.78 atm.

Hope this helps!
