Density is an intensive physical property that relates the mass of an object to its volume. density, which is simply the mass of an object divided by its volume, is expressed in the si derived unit g/mlg/ml for a liquid or g/cm3g/cm3 for a solid. most substances expand or contract when heated or cooled, so the density values for a substance are temperature dependent. a particular brand of gasoline has a density of 0.737 g/ml at 25 ? c. how many grams of this gasoline would fill a 14.6gal tank?

40731.8 grams of this gasoline would fill a 14.6gal tank

Explanation:

Density is defined as the mass contained per unit volume.

Given : Mass of gasoline = ?

Density of the gasoline =

Volume of the gasoline = 14.6gal = 55267.01 ml           (1gal=3785.41ml)

Putting in the values we get:

Thus 40731.8 grams of this gasoline would fill a 14.6gal tank

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
