Answer:

89.3 mL

Explanation:

First we convert 20.0 °C and 54.0 °C to K:

  • 20.0 °C + 273.16 = 293.16 K
  • 54.0 °C + 273.16 = 327.16 K

With the absolute temperatures we can solve this problem by using Charles' law:

  • T₁V₂=T₂V₁

Where in this case:

  • T₁ = 293.16 K
  • V₂ = ?
  • T₂ = 327.16 K
  • V₁ = 80.0 mL

We input the data:

  • 293.16 K * V₂ = 327.16 K * 80.0 mL

And solve for V₂:

  • V₂ = 89.3 mL
