Why are the densities of corn syrup and gasoline expressed as a rang of values?

The densities of corn syrup and gasoline are expressed as a range of values because these substances can vary in composition and temperature. Factors such as the concentration of sugars in corn syrup or the specific blend of hydrocarbons in gasoline can influence their densities. Additionally, temperature variations can affect the density of liquids, leading to changes in measurements. Therefore, expressing density as a range accounts for these variables and provides a more accurate representation of their properties under different conditions.
