Answer to Question #114602 in General Chemistry for vanessa

Question

800 mmhg how many liters would this same gas occupy at a pressure of 0.75 atm at constant tempeture and omount o gas

Answer 1

We have T = const and n = const. According to the Boyle's law:

pV = const, from here:

p₁V₁ = p₂V₂

For further calculations we need the initial volume of gas (V₁). Wr have p₁ = 800 mmhg = 1.05 atm and p₂ = 0.75 atm.

V₂ = p₁V₁/p₂ = V₁*1.05/0.75 = 1.4 V₁

So, gas with volume V₁ at 800 mmHg would occupy volume 1.4 V₁ at 0.75 atm.
