Answer:
10 mm Hg
Explanation:
We can solve this problem using Boyle's law, which states that at a constant temperature:
P₁V₁=P₂V₂The subscript 1 stands for the initial conditions and 2 for the final conditions.
In this case:
P₁ = ?V₁ = 300.0 mLP₂ = 30.0 mm HgV₂ = 100.0 mLWe input the data:
P₁ * 300.0 mL = 30.0 mm Hg * 100.0 mLAnd solve for P₁:
P₁ = 10 mm Hg
