Answer:

Explanation:
The density formula is:

Let's rearrange the formula for
. the volume. Multiply both sides by
, then divide by
.




The volume can be found by dividing the mass by the density. The mass of the object is 30.07 grams and the density is 1.48 grams per milliliter.


Divide. Note, when dividing, the grams, or
will cancel out.


The volume of the object is 20.317567567568 milliliters.
Answer:
The answer is
<h2>4.54 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of rock = 454 g
volume = 100 cm³
The density of the rock is

We have the final answer as
<h3>4.54 g/cm³</h3>
