Question

An Erlenmeyer flask holds
19.0 g of a liquid that takes
up a volume of 25.0 mL.
What is the density of the
liquid?

Answer 1

Taking into account the definition of density, the density of the liquid is 0.76 $\frac{g}{mL}$.

First of all, 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.

In this case, you know:

• mass= 19 g
• volume =25 mL

So, replacing in the definition of density:

$density= \frac{19 g}{25 mL}$

Solving:

$density= 0.76 \frac{g}{mL}$

Finally, the density of the liquid is 0.76 $\frac{g}{mL}$.
