Density$= 1.39 \text{g"/"mL}$

#### Explanation:

Density is defined as the relationship between the mass of some substance/material and how much space it takes up, or volume.

The equation for density is as follows:

$d = \frac{m}{v}$ OR $\text{Density"="mass"/"volume}$

Where in this example,

• $m$ is the mass of the substance in $\text{g}$

• $v$ is the volume in $\text{mL}$

• And $d$ is the density expressed in units of $\text{g"/"mL}$

Going back to the actual problem we are to find the density of a material given that:

• The material has a mass of $4.97 \text{g}$
• It occupies $3.57 \text{mL}$ in volume

The problem gives us the mass and the volume of the material so all we have to do to find its density is substitute these values into our formula and compute.

Therefore,

$d = \left(4.97 \text{g")/(3.57"mL}\right)$

$d = 1.39 \text{g"/"mL}$

The density of this material is thus $1.39 \text{g"/"mL}$
