Answer:
0.494 atm
Explanation:
Data obtained from the question include:
P1 (initial pressure) = 0.987 atm
V1 (initial volume) = 12.8 L
P2 (final pressure) =?
V2 (final volume) = 25.6 L
Using the Boyle's law equation P1V1 = P2V2, the final pressure can be obtained as follow:
P1V1 = P2V2
0.987 x 12.8 = P2 x 25.6
Divide both side by 25.6
P2 = (0.987 x 12.8) /25.6
P2 = 0.494 atm
Therefore, the final pressure of the gas is 0.494 atm
