The density of gold is 19.3 g/cm3. a piece of gold displaces 2 ml of water. the specific gravity of gold is: a.19.3 b.38.6 c.9.6 d.0.10

A) 19.3

Explanation:

As we know that specific gravity is defined as the ratio of weight of the object and weight of the water displaced by the object

so it is given by

now we have

weight of the object = (density)(volume)g

weight of object =

now weight of the liquid displaced is given by

weight of water displaced =

now we have

specific gravity =

specific gravity = 19.3

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

what is the actual question though?
