Answer:

455.4 mmHg

Explanation:

To solve this problem we can use Gay Lussac's Law, which describe the temperature and pressure of a gas, at constant volume and composition:

  • P₁T₂ =  P₂T₁

In this case:

  • P₁ = 621 mmHg
  • P₂ = ?
  • T₁ = 315 K
  • T₂ = 231 K

We input the data:

  • 621 mmHg * 231 K = P₂ * 315 K

And solve for P₂:

  • P₂ = 455.4 mmHg
