The specific gravity of gasoline is approximately 0.75. Specific gravity is a measure of the density of a substance compared to the density of water, which has a specific gravity of 1. This means that gasoline is lighter than water, as confirmed by its specific gravity being less than 1.

Understanding specific gravity is vital for firefighters, as it helps in assessing the behavior of gasoline in spills and fires. Since gasoline typically floats on water, knowing its specific gravity aids in predicting how it will spread and how to effectively contain it in emergency situations.

In this case, the answer of 0.75 reflects the commonly accepted value for the specific gravity of gasoline, which is important for safety protocols related to its handling and storage. The other values are not aligned with the standard characteristics of gasoline, hence they do not represent the accurate specific gravity of this substance.
