a gas occupies 100.0 mL at a pressure of 780 mm Hg. What is the pressure of the gas when its volume is decreased to 25.0 mL?

Respuesta :

Answer:

[tex]P_2=3120mmHg[/tex]

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:

[tex]P_1V_1=P_2V_2[/tex]

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

[tex]P_2=\frac{P_1V_1}{V_2} =\frac{780mmHg*100.0mL}{25.0mL}\\\\P_2=3120mmHg[/tex]

Best regards!
