Answer:
The correct answer is 0.536 atm.
Explanation:
The formula to use to solve the given question is,
P1V1 = P2V2
Based on the given information, the initial pressure (P1) of the oxygen gas is 0.656 atm, the initial volume (V1) is 10.7 L. The new volume (V2) given is 13.1 L, there is a need to find the new pressure of the gas (P2).
Now putting the values in the above equation we get,
0.656 atm * 10.7 L = P2 * 13.1 L
P2 = 0.656 atm*10.7 L/13.1 L
P2 = 0.536 atm
