Answer to Question #110343 in Chemistry for Randi Celedon

Question

What is the final volume of a system that has the volume increased from 3.16l to 6.97l with an initial pressure of 3.38atm?

Answer 1

Most likely, a technical mistake was made in the task and we need to find the final pressure of the system, and not the final volume.

P₁ = 3.38 atm;

V₁ = 3.16 L;

P₂ = unknown;

V₂ = 6.97 L.

Solution:

1) Let's use this equation:

P₁V₁ = P₂V₂ (Boyle’s Law).

Temperature is constant.

2) Let's insert values:

(3.38 atm * 3.16 L) = (P₂ * 6.97 L).

Then,

P₂ = (3.38 atm * 3.16 L) / (6.97 L) = 1.53 atm.

P₂ = 1.53 atm.

Answer: 1.53 atm is the final pressure of a system.
