g A sample of chlorine gas starting at 681 mm Hg is placed under a pressure of 991 mm Hg and reduced to a volume of 513.7 mL. What was the initial volume, in mL, of the chlorine gas container if the process was performed at constant temperature?

Answer:

747.5 mL

Explanation:

Assuming ideal behaviour, we can solve this problem by using Boyle's law, which states that at constant temperature:

  • P₁V₁ = P₂V₂

Where in this case:

  • P₁ = 681 mm Hg
  • V₁ = ?
  • P₂ = 991 mm Hg
  • V₂ = 513.7 mL

We input the data given by the problem:

  • 681 mm Hg * V₁ = 991 mm Hg * 513.7 mL

And solve for V₁:

  • V₁ = 747.5 mL
