If the pressure of a 2.00 L sample of gas is 50.0 kPa, what pressure does the gas exert if its volume is decreased to 20.0 mL?

Which equation should you use?

Which equation should you use?

B. P₁V₁=P₂V₂

What is the new pressure?  

✔ 5000  kPa

Explanation:

The problem gives initial volume (2.00 L), final volume (20.0 mL), and initial pressure (50.0 kPa). Then it asks to find the final pressure. Answer B has all these variables, with P₁=initial pressure, P₂=final pressure, V₁=initial volume, and V₂=final volume. Plug the given values into the equation and then solve for the unknown value, which is P₂, final pressure.

When plugging in the values, use consistent units. 2L=2000 mL, I chose to make the consistent unit in mL. You'll get the same answer if you choose to use L as the consistent unit.

[tex]2000*50=20*P2[/tex]

[tex]100000=20*P2[/tex]

Divide both sides by 20

[tex]100000/20=(20*P2)/20[/tex]

[tex]5000=P2[/tex]
