Question

A 7.10-L sample of gas at (308K.0.146 atm) is allowed to expand so that the final pressure is 0.0832 atm. Assuming constant temperature, calculate the final volume of Answer: Note: you may enter your answer in Enotation. Example: 1.5x10-in E notation is 1.5E-6. Example: 1036, which is the same as 1x1036, in E notation is 1E36.)

Answer 1

any query please comment.

Given, Initial volume = 7.10L (V) At tempereture = 300k Initial pressure = 0.14 6 atm (Pi) Final pressure = 0.0832 atm (P2) final volume = ? (V2) Since , temperature remaining constant there fore we can u we will use Boyle's law equation according to Boyle's law, P, VI = P₂ V2 where P, and are Initial pressure and volume similarly P2 and 2 are final pressure and volume. Now, here P = 0.146 atm P2=0.0832 atm = 7. lol. V2 = ? Nowa PV = P2 V2 0.146 atm x 7. ol = 0.0832 atm x V₂ V = 0.146 atm x 7100 0.0832 atm = 12.46 a l (Ans)

If satisfied please rate it. Thanku.
