GuDViN [60]

Answer:

The density of the substance is 1.0611 $\frac{g}{cm^{3} }$

Explanation:

The density of a substance is a characteristic property that matter, whether solids, liquids or gases, has to be compressed in a given space, that is, it allows us to measure the amount of mass in a certain volume of a substance.

Density is expressed as follows:

$density=\frac{mass}{volume}$

In this case:

density: ?
mass: 21.1164 grams
volume: 19.9 cm³

Replacing:

$density=\frac{21.1164 grams}{19.9 cm^{3} }$

density= 1.0611 $\frac{g}{cm^{3} }$

<u><em>The density of the substance is 1.0611 </em></u> $\frac{g}{cm^{3} }$ <u><em></em></u>
