Chemistry- Boyle's Law

Question

Once you’ve identified the initial and final conditions, you’re ready to solve for the unknown quantity in your problem. Boyle’s Law expresses the pressure-volume relationship as P1V1=P2V2 , so you will need to solve this equation for the unknown quantity and then plug in your known values to calculate the unknown.

What pressure would it take to compress 350. L of helium gas initially at 1.00 atm  into a 2.00 L  tank at constant temperature?

Answer 1

P1 = 1.00 atm

V1 = 350. L

P2 = ?

V2 = 2.00 L

P1V1 = P2V2

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

P2 = 175 atm
