Explanation:
Taking into account the definition of density, the density of the sample is 0.5
.
It is necessary yo know that density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.
In other words, density allows you to measure the amount of mass in a certain volume of a substance.
Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
![density=\frac{mass}{volume}](https://tex.z-dn.net/?f=density%3D%5Cfrac%7Bmass%7D%7Bvolume%7D)
In this case, you know:
Then, replacing in the definition of density:
![density=\frac{6 g}{12 mL}](https://tex.z-dn.net/?f=density%3D%5Cfrac%7B6%20g%7D%7B12%20mL%7D)
Solving:
<u><em>density= 0.5 </em></u>
<u><em /></u>
Finally, the density of the sample is 0.5
