Question

At a constant temperature, a sample of a gas in a balloon that originally had a volume of 5.00 L and pressure of 626 torr has its volume changed to 6.72 L. Calculate the new pressure in torr.

Answer 1

466 torr

Step-by-step explanation:

Step 1: Given data

• Initial pressure (P₁): 626 torr

• Initial volume (V₁): 5.00 L

• Final pressure (P₂): ?

• Final volume (V₂): 6.72 L

• Constant temperature

Step 2: Calculate the final pressure

Since we have a gas changing at a constant temperature, we can calculate the final pressure using Boyle's law.

P₁ × V₁ = P₂ × V₂

P₂ = P₁ × V₁ / V₂

P₂ = 626 torr × 5.00 L / 6.72 L

P₂ = 466 torr
