Final answer:
The correct answer to the Chemistry question regarding the manipulation of gas volume under Boyle's Law is D. 6.0 L. At constant temperature, doubling the pressure from 380 torr to 760 torr will halve the volume of the gas from 12 liters to 6.0 liters.
Step-by-step explanation:
The subject is Chemistry, and the question involves the application of Boyle's Law, which states that at constant temperature, the volume of a fixed mass of gas is inversely proportional to its pressure. In this case, when the pressure on a sample of gas is doubled from 380 torr to 760 torr at a constant temperature, the volume will be halved.
Using the formula P1V1 = P2V2, where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume respectively, we can calculate the new volume of the gas.
Substituting the values:
- P1 = 380 torr
- V1 = 12 liters
- P2 = 760 torr
- V2 = ?
So, (380 torr)(12 L) = (760 torr)(V2), solving for V2 gives us V2 = 6.0 L. Thus, the new volume of the gas when the pressure is changed to 760 torr is 6.0 L. Therefore, the correct answer is D. 6.0 L.
