Question

1. A sample of gas was compressed at 35 °C from a volume of 300.0 mL to a volume

Answer 1

Answer:

10 mm Hg

Explanation:

We can solve this problem using Boyle's law, which states that at a constant temperature:

• P₁V₁=P₂V₂

The subscript 1 stands for the initial conditions and 2 for the final conditions.

In this case:

• P₁ = ?

• V₁ = 300.0 mL

• P₂ = 30.0 mm Hg

• V₂ = 100.0 mL

We input the data:

• P₁ * 300.0 mL = 30.0 mm Hg * 100.0 mL

And solve for P₁:

• P₁ = 10 mm Hg
