Which noun is commonly used to describe the amount of a substance that can be measured in liters or gallons?

• A. Volume
• B. Mass
• C. Length
• D. Density

Answer: (A)

Think about what the units are labeling. Liters and gallons tell you how much space something occupies or how much it can hold, which is volume. Volume describes the amount of a substance in terms of space, and we typically use liters or gallons for liquids or containers. Mass, on the other hand, measures how much matter there is and uses grams or kilograms. Length measures distance, not quantity, and density describes how much mass is packed into a given volume, not the total amount itself. So when you’re talking about the amount described in liters or gallons, you’re referring to volume. For example, a bottle with 2 liters of water has a volume of 2 liters.
