To calculate the density of an object, you can use the formula:

$\text{Density} = \frac{\text{Mass}}{\text{Volume}}$

Given:

• Mass = 120 g
• Volume = 7 mL

Now, substitute the values into the formula:

$\text{Density} = \frac{120 \, \text{g}}{7 \, \text{mL}} \approx 17.14 \, \text{g/mL}$

So, the density of the object is approximately 17.14 g/mL.
