Quizplus · Accepted Answer

Using Boyle's Law, we can relate the initial pressure and volume to the final pressure and volume.

P1V1 = P2V2

where P1, V1, and P2 are the initial pressure, initial volume, and final pressure, respectively, and V2 is the final volume we're trying to find.

Substituting the given values:

11.8 atm x 750.0 mL = 2.6 atm x V2
V2 = (11.8 atm x 750.0 mL) / (2.6 atm) = 1.750 L

Therefore, the final volume the gas occupies is 1.750 L, which corresponds to choice (C).

The Initial Volume of a Gas Cylinder Is 750
