Answer :
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
