The gas tank of a certain luxury automobile holds 22.3 gallons according to the owner's manual. if the density of gasoline is 0.8206 g/ml, determine the mass in kilograms and pounds of the fuel in a full tank.

Explanation:

It is known that,

            1 gallon = 3785.41 ml

So,      22.3 gallons =

                                = 84414.64 ml

Also, we know that density is mass of substance divided by its volume. Therefore, calculate the mass of given gasoline as follows.

                     Density =

            0.8206 g/ml =

                 mass = 69270.65 g

As 1 g = 0.001 kg. Hence, calculates mass is converted into kg as follows.

                  = 69.27 kg

Thus, we can conclude that mass of given gasoline is 69.27 kg.
