    Answer:

    P_2=3120mmHg

    Explanation:

    Hello there!

    In this case, according to the Gay-Lussac’s law, which sets up the pressure-volume behavior as a directly proportional relationship:

    P_1V_1=P_2V_2

    Thus, since we are asked for the final pressure, P2, we obtain:

    P_2=\frac{P_1V_1}{V_2} =\frac{780mmHg*100.0mL}{25.0mL}\\\\P_2=3120mmHg

    Best regards!
