Density is defined as the ratio of mass to the volume.
Density =
(1)
Mass of water = 10 grams
Mass of acetone = 10 grams
Density of water = 1 ![\frac{g}{cm^{3}}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bg%7D%7Bcm%5E%7B3%7D%7D%20)
Density of acetone = 0.7857 ![\frac{g}{cm^{3}}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bg%7D%7Bcm%5E%7B3%7D%7D%20)
Put the value of density of water and its mass in equation (1)
1
= ![\frac{10 g}{volume}](https://tex.z-dn.net/?f=%20%5Cfrac%7B10%20g%7D%7Bvolume%7D%20)
Volume of water = 10 ![cm^{3}](https://tex.z-dn.net/?f=%20cm%5E%7B3%7D%20)
Put the value of density of acetone and its mass in equation (1)
0.7857
= ![\frac{10 g}{volume}](https://tex.z-dn.net/?f=%20%5Cfrac%7B10%20g%7D%7Bvolume%7D%20)
Volume of acetone = 12.72 ![cm^{3}](https://tex.z-dn.net/?f=%20cm%5E%7B3%7D%20)
Thus, volume of acetone is more than volume of water because the density of acetone is lower.
<u>Answer</u>:
the continents of earth were clustered together in formation that a scientist named Pangaea.
<u>Explanation</u>:
Before 300 million years ago, our earth was not made up of 7 different continent what we have now. Instead it was single huge mass land that was surrounded by a single ocean called Panthalassa. A lot of migration and collision lead to the formation of Pangaea. An Scientist named Albert Wegener gave the name Pangaea. Later, Pangaea was broken into Gondwanaland and Laurasia.These Lands were then divided into 7 continents.
