Here's how to solve this problem using Boyle's Law:

Boyle's Law states that the pressure of a gas is inversely proportional to its volume, assuming constant temperature. Mathematically:

P₁V₁ = P₂V₂

Where:

* P₁ = Initial pressure

* V₁ = Initial volume

* P₂ = Final pressure

* V₂ = Final volume

Let's plug in the values:

* P₁ = 0.988 atm

* V₁ = 1.00 L

* V₂ = 4.40 L

* P₂ = ?

Solve for P₂:

0.988 atm * 1.00 L = P₂ * 4.40 L

P₂ = (0.988 atm * 1.00 L) / 4.40 L

P₂ ≈ 0.225 atm

Therefore, the new pressure of the helium sample in the 4.40 L container is approximately 0.225 atm.
