Question

What pressure would it take to compress 200 L of helium gas initially at 1.00 atm into a 2.00 L tank at constant temperature?

Answer 1

You are given an initial volume (350 L) and an initial pressure (1.00 atm). The temperature is constant, and you are asked to find a final pressure given a final volume of 2.00 L. For this, you can use P1V1 = P2V2.

(1.00 atm)(350 L) = (P2)(2.00 L)

P2 = 175 atm
