Agata [3.3K]3 years ago
3 0

Answer:

89.3 mL

Explanation:

First we <u>convert 20.0 °C and 54.0 °C to K</u>:

  • 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 <em>Charles' law</em>:

  • T₁V₂=T₂V₁

Where in this case:

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

We <u>input the data</u>:

  • 293.16 K * V₂ = 327.16 K * 80.0 mL

And <u>solve for V₂</u>:

  • V₂ = 89.3 mL
