Answer:
The density of the substance is 1.0611 
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:
In this case:
- density: ?
- mass: 21.1164 grams
- volume: 19.9 cm³
Replacing:
density= 1.0611
<u><em>The density of the substance is 1.0611 </em></u><u><em></em></u>

Explanation:
Continental drift is the movement of Earth’s continents over long periods of time. An evidence for this is that some continents look like puzzle pieces that can fit together, such as South America and Africa.

Another evidence is that identical rocks were found at both sides of the Atlantic Ocean by Alfred Wegener, the main developer of the continents drift theory.
