Answer 1

9.7atm

Step-by-step explanation:

Ideal gas laws let us find different characteristics of gas through its changes.

Boyle's Law

Boyle's law describes the relationship between pressure and volume. This law states that volume and pressure are inversely proportional. This means that as volume increases, pressure decreases. In equation form, Boyle's law is:

• P₁V₁ = P₂V₂

In the question, the new volume is greater than the original. This means that the new pressure must be less than the original pressure.

Solving for P₁

In order to find the original pressure, we can plug in the information we know.

• P₁ * 4.0L = 4.3atm * 9.0L

Now, divide both sides by 4.0L.

• P₁ ≈ 9.675atm

This pressure is greater than 4.3atm, which follows the prediction we made earlier. So, this is a reasonable answer. Since this question involves measured values, we should round according to significant figure rules. This means that the original pressure is 9.7atm.
