A Tesla roadster electric vehicle has a MPGe (Miles per Gallon equivalent) of 102 miles per gallon. A Ford F-150 has a rating of 21 MPG. The weight of the electric battery in the Tesla is 1062 lb. The volume of the gas tank in the F-150 is 83.2791 L. The density of gasoline is 748.90002 kg/m³. Which weighs more, the battery in the Tesla or the gasoline in the F-150.?

The battery in the Tesla weighs more

Explanation:

Mass = Density × volume

Density of gasoline = 748.90002 Kg/m³

Volume of tank in m³ = 83.2791/1000 = 0.0832791 m³

Mass of gasoline in F-150 = 748.90002 × 0.0832791 = 62.3771 Kg

Converting mass in Kg to lb

Mass of gasoline (lb) = 62.3771 × 2.204623

Mass of gasoline (lb) = 137.51 lb

Weight of battery in Tesla = 1062 lb

Comparing the two shows that the battery of the Tesla weighs more.

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.
