The complete question is: A chemist reported that 100 gallons of gas were available in a laboratory which property of the gas to the chemist report?

A. Length

B. Mass

C. Temperature

D. Volume

However, regardless of the options, you can see that the gallon is a unit of volume that is used in Anglophone or influenced countries and in several Latin American countries (such as Nicaragua and Panama, among others), to measure volumes of liquids such as fuel, milk, wine or beer.

The interesting thing about this measure is that it is not the same to speak of a British gallon than a gallon in America. A US gallon equals 3,785 liters while the imperial or British gallon equals 4, 546 liters.

Then, the chemist reported a unit of volume.
