Substance a and b are colorless, odorless liquids that are nonconductors and flammable. the density of substance a is 0.97 g/ml; the density of substance b is 0.89 g/ml. are a and b the same substance? explain your answer.

A and B are not the same substances.

The reason is because they do not have the same density which is a function of their masses and volumes.

For instance, for every Volume of 1mL of each substances, A has a mass of 0.97g which is different from the 0.89g of B.

i believe that it is a exoplanet

dynamic equilibrium is the answer.
