Answer: Salt is a pure substance. Pure substances are composed of one type of molecule. All of the substances listed are composed of two or more types of molecules, except for salt. Therefore, salt would be your answer.

Hope this helps.

The planet Saturn has a mass of 5.69x10 26 and volume 8.01x10 23 m3 what is the density of Saturn ? Would Saturn sick or float i
Ad libitum [116K]

Density = mass/volume

We are given a mass (which I am assuming is in kilograms) and a volume.  Divide to find density.

Density of Saturn = 5.69x10²⁶ kg / 8.01x10²³ m³

Density of Saturn = 710. kg/m³

The density of water is 1000 kg/m³, which is higher than the density of Saturn.  Since Saturn has a lower density than water, theoretically, Saturn would float in a gigantic bathtub filled with water.

<h3>Answer:</h3>

Density: 710. kg/m³

Float? Yes.
