Question

A sample of oxygen gas occupies a volume of 229.5 mL at 762.7 torr pressure. What volume in mL will it occupy at 704.5 torr pressure?

Answer 1

Answer:

248.4 mL

Explanation:

In order to answer this problem we can use Boyle's law, which states that at a constant composition:

• P₁V₁ = P₂V₂

Where in this case:

• P₁ = 762.7 torr

• V₁ = 229.5 mL

• P₂ = 704.5 torr

• V₂ = ?

We input the data:

• 762.7 torr * 229.5 mL = 704.5 torr * V₂

And solve for V₂:

• V₂ = 248.4 mL
