Final answer:
To determine the pressure needed to bring the volume to 2.5 L, we can use Boyle's Law. By substituting the given values into the equation, we find that the pressure needed is 6.72 atm.
Step-by-step explanation:
To determine the pressure needed to bring the volume to 2.5 L, we can use Boyle's Law, which states that the pressure and volume of a gas are inversely proportional at constant temperature.
Boyle's Law can be expressed as:
P1V1 = P2V2
Where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume.
Now, we can substitute the given values into the equation:
2.8 atm x 6.0 L = P2 x 2.5 L
Solving for P2, we get:
P2 = (2.8 atm x 6.0 L) / 2.5 L = 6.72 atm
Therefore, the pressure needed to bring the volume to 2.5 L is 6.72 atm.
