algol13

Answer:

P_2=135.73psi

Explanation:

Hello,

In this case we use the Boyle's law which allows us to understand the volume-pressure behavior as an inversely proportional relationship:

V_1P_1=V_2P_2

Whereas we solve for P_2 as the required final pressure:

P_2=\frac{V_1P_1}{V_2} =\frac{27.0L*14.7psi}{3.00L}\\ \\P_2=135.73psi

Best regards.
