Answer:

80.5 atm

Explanation:

First of all, we convert 28.0 °C and 50.0 °C into K:

  • 28.0 + 273.16 = 301.16 K
  • 50.0 + 273.16 = 323.16 K

To answer this problem we'll use Gay-Lussac's Law, which states that:

  • T₁*P₂=T₂*P₁

In this case:

  • T₁ = 301.16 K
  • P₂ = ?
  • T₂ = 323.16 K
  • P₁ = 75.0 atm

We put the data:

  • 301.16 K * P₂ = 323.16 K * 75.0 atm

And solve for P₂:

  • P₂ = 80.5 atm

Thus, the correct answer is 80.5 atm.
