Answer:
1.23 atm
Explanation:
Given data
- Initial pressure (P₁): 1.0 atm
- Initial volume (V₁): 750 mL
- Final pressure (P₂): to be calculated
- Final volume (V₂): 610 mL
For a gas sample, <em>there is an inverse relationship between the pressure and the volume</em>, that is, when the pressure is increased, the volume decreases. Mathematically, for an ideal gas at constant temperature, we can find the final pressure using Boyle's law.
