Answer to Question #156031 in General Chemistry for Taitafe Fuamatu

Question

 A 2.0 -L sample of gas at 650 mmHg pressure is expanded until its volume is 4.5 L.

What is the pressure in the expanded gas sample (at constant temperature)?

Answer 1

P₁V₁=P₂V₂

P₁=650mmHg

V₁=2.0L

V₂=4.5L

P₂=?

650×2.0=4.5P₂

P₂=650×2.0/4.5

P₂=288.9mmHg
