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:

2220 Torr

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
