Using a conversion factor of approximately 0.31 L per psi, how many liters remain in a cylinder at 1000 psi?

• A. 310 L
• B. 320 L
• C. 350 L
• D. 400 L

Answer: (A)

In this context, the amount of gas left in a standard cylinder is estimated by multiplying the pressure (in psi) by a conversion factor that gives liters per psi. With a factor of 0.31 L per psi, the remaining volume at 1000 psi is 1000 × 0.31 = 310 liters. This straightforward multiplication reflects the fixed-cylinder relationship between pressure and gas volume when temperature and cylinder size are constant, so 310 L is the correct estimate. The other numbers would require a different conversion factor or pressure.
