Answer:
1.661 atm
Explanation:
Data obtained from the question include:
P1 (initial pressure) = 0.867 atm
V1 (initial volume) = 18.6 L
V2 (final volume) = 9.71 L
P2 (final pressure) =?
Since the temperature is constant, the gas is obeying Boyle's law. Now using the Boyle's law equation P1V1 = P2V2, we can calculate the final pressure as shown below:
P1V1 = P2V2
0.867 x 18.6 = P2 x 9.71
Divide both side by 9.71
P2 = (0.867 x 18.6) /9.71
P2 = 1.661 atm
Therefore, the final pressure of the gas is 1.661 atm
