You would get 12 in/ft.

I was going to use 8.314 K-1mol-1 since that is the gas constant for air. I looked through my textbook and found that °R = °F + 459.67, so I would do 70°F + 460 = °R. Would I do something with the volume to get the 144? I am not even sure what that number is doing there since the equation just...
