A closed, adjustable cylinder containing 6.2 moles of oxygen gas has a volume of 8.4 liters and a pressure of 5.0 atmospheres. If the cylinder's volume is changed to 14.3 liters, what is the new pressure of the gas? Round your answer to the nearest 0.01 atm.

Answer :

answer and explanation

to determine the new pressure we can use Boyle's Law which states that

P1V1 = P2V2

P1 = 5.0atm

V1 = 8.4LP2?

V2 = 14.3L

P2 = P1V2/V1

= (5.0 x 14.3) / 8.4

= 8.51 atm
