Question

A 54.9 L sample of nitrogen gas experiences a change in pressure from 87.0 kPa to 149.7 kPa. What is the resulting volume in liters if the temperature changes from 27^oC to 59^oC?

Answer 1

Hello, Molly,

Please explain what part of the gas laws is causing confusion. I've provided the correct equation and demonstrated how to rearrange for the desired variable in previous answers. The unknown in this case is V2

V2=V1(T2/T1)(P1/P2)

Enter the data given and solve for V2. Pressure goes up, so that will reduce volume. Temperature also goes up, but that will decrease the volume. It's a little hard to judge which will "win," but the pressure increase looks like the greatest change, so I'll predict the volume will decrease.

I get V2 = 35.3 L
