How many liters of 92 gasoline can a 25 kg barrel hold?

[AndrewDella]

25 kg barrel can hold 25 liters of 92 gasoline, with a mass of approximately 18.475 kg. The density of water is 1000 g/cubic decimeter. 1 cubic decimeter = 1 liter, so the capacity of a 25 kg barrel is equal to 25 liters. However, the densities of water and gasoline are different. A 25 kg barrel can hold 25 liters of water, but if filled with gasoline, it would be less than 25 liters. Formula for gasoline density: The density of gasoline = 0.739 g/ml (0.739 grams/milliliter). According to the formula: mass = volume × density, the mass of gasoline is approximately 18.475 kg. Concepts of volume and capacity: Volume and capacity are not the same concept. If 25 kg of water is converted to a capacity of 25 liters (specific gravity of water is 1), the specific gravity of gasoline is 0.75, so the gasoline would only occupy 75% of the water's capacity.
