Hello, Jalen,
Since the moles of gas (hellum is a hell of a gas. I suggest you try helium, instead) do not change between the two sets of conditions, we can use:
P1V1/T1 = P2V2/T2
Rearrange to solve for the unknown:
P2 = P1(V1/V2)(T2/T1)
The temperature does not change, so this is quickly becoming earier:
P2 =P1(V1/V2)(T2/T1)
Enter the data for V1,, V2, and P1. Just looking at what the equation is suggesting, the pressure should go down if the volume goes up. The trouble here is that the volumes also stay the same, 1.97 liters.
Trick question? Maybe, then P1 = P2
Otherwise, enter the correct volumes and solve.
Bob
