maria [59]

Answer:

The volume of the gas will be 573.52 mL.

Explanation:

Boyle’s law states that <u>the  pressure of a fixed amount of gas at a constant temperature is inversely proportional  to the volume of the gas</u>.

The equation for Boyle's law is:

P₁V₁ = P₂V₂

We want to know V₂, that is, the volume of the container after the compression. We rearrange the equation and calculate:

V₂ = P₁V₁ ÷ P₂

V₂ = 1.14 atm × 815 mL ÷ 1.62 atm = 573.52 mL
