50. A cargo of fuel oil is loaded whose temperature is 66°F. API gravity is 36°. The volume correction factor (VCF) is .0005. A cargo temperature of 80°F is expected at the discharge port. If 9,000 barrels were loaded, how many gallons would you expect to unload?

The correct answer is 380,646 gallons. This result is obtained by applying the volume correction factor to the initial volume of 9,000 barrels, accounting for thermal expansion due to the temperature increase, and then converting the expanded volume to gallons using a conversion factor of 42 gallons per barrel.
