Taking into account the definition of density, the density of the sample is 0.5 \frac{g}{mL}.

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}

In this case, you know:

  • mass= 6 g
  • volume= 12 mL

Then, replacing in the definition of density:

density=\frac{6 g}{12 mL}

Solving:

<u><em>density= 0.5 </em></u>\frac{g}{mL}<u><em /></u>

Finally, the density of the sample is 0.5 \frac{g}{mL}.
