Answer to Question #31461 in Inorganic Chemistry for Shay

Question

A 2.50L sample of carbon monoxide gas has a pressure of 835mmHg. Assuming the temperature remains constant, what is the final pressure if the volume is changed to 6.35L?

Answer 1

Carbon monoxide gas that has a pressure of 835 mm Hg will be 908.38764 Pa.
Using the Ideal Gas equation:
PV = nRT, from this:
Where:
P - pressure
V - volume
At the T - const:
P₁V₁ = P₂V₂, from this equiation:
P₂ = P₁*V₁/(V₂)
P₂ = 908.38764 Pa x 2.5 L/(6.35 L)
P₂ = 2270.95/6.35
P₂ = 357.63 Pa

Answer: 357.63 Pa
