Question

A 10.0 L balloon contains helium gas at a pressure of 655 mmHg. What is the final pressure, in millimeters of mercury, if the final volume is 13.8 L? Please show your work in order to receive credit.

Answer 1

474. 64 mm Hg

Step-by-step explanation:

• P1 = 655 mm Hg
• V1 = 10 L

• P2 = ?
• V2 = 13. 8 L

using Boyle's Law that is

P1. V1 = P2. V2

655 × 10 = P2 × 13. 8

`P2 = (655 * 10)/(13.8)`

P2 = 474. 64 mm Hg
