Assume a gasoline is isooctane, which has a density of 0.692 g/ml. what is the mass of 3.8 gal of the gasoline (1 gal = 3.78 l)?

Density is the ratio of mass to the volume.

The mathematical expression is given as:

Now, density of isooctane =

Volume  =

Since, 1 gallon = 3.78 L

So, 3.8 gal =

=

As, 1 L = 1000 mL

Therefore, =

Volume in mL =

Put the values,

=

Hence, mass of 3.8 gal of the gasoline is .
