Question

Carbon tetrachloride is a solvent used for degreasing electronic parts. If 24.0 mL of carbon tetrachloride has a mass of 38.10 g , what is the density of the liquid

Answer 1

Taking into account the definition of density, the density of carbon tetrachloride is 1.5875 $\frac{g}{mL}$.

Definition of density

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us 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:

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

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

Density of carbon tetrachloride

In this case, you know that:

• Mass= 38.10 g
• Volume= 24 mL

Replacing in the definition of density:

$density=\frac{38.10 g}{24 mL}$

Solving:

density= 1.5875 $\frac{g}{mL}$

In summary, the density of carbon tetrachloride is 1.5875 $\frac{g}{mL}$.
