Question

The sample of oxygen gas is compressed from 5.25L to 1.75L. If the original pressure was 740. Torr, what is the final pressure?

Answer 1

2220 Torr

Step-by-step explanation:

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

• V₁P₁=V₂P₂

Where subscript 1 refers to the initial volume and pressure, while subscript 2 refers to the final state, meaning that in this case:

• V₁ = 5.25 L

• P₁ = 740 Torr

• V₂ = 1.75 L

• P₂ = ?

We input the data:

• 5.25 L * 740 Torr = 1.75 L * P₂

• P₂ = 2220 Torr
