Answer:
463.64L
Explanation:
The following data were obtained from the question:
V1 (original volume) = 85L
P1 (original pressure) = 1.2 atm
P2 (new pressure) = 0.22 atm
V2 (new volume) =?
Since the temperature is constant, the gas is obeying Boyle's law.
Using the Boyle's law equation P1V1 = P2V2, the new volume of the gas can obtain as follow:
P1V1 = P2V2
1.2 x 85 = 0.22 x V2
Divide both side by 0.22
V2 = (1.2 x 85)/0.22
V2 = 463.64L
Therefore, the new volume is 463.64L
