To solve this problem, we can use Boyle's Law, which states that the pressure and volume of a gas are inversely proportional at constant temperature. Boyle's Law can be expressed as:
P₁V₁ = P₂V₂
where P₁ and V₁ are the initial pressure and volume, and P₂ and V₂ are the final pressure and volume.
Given: P₁ = 950 torr V₁ = 800 mL P₂ = 800 torr
We need to find V₂, the final volume.
Using Boyle's Law, we can rearrange the equation to solve for V₂:
V₂ = (P₁V₁) / P₂
Plugging in the values:
V₂ = (950 torr * 800 mL) / 800 torr
V₂ = 950 mL
Therefore, the volume of the neon gas sample would be 950 mL if the pressure is decreased to 800 torr.
