Answer:
The answer is
3.0 g/cm³
Explanation:
To find the density of a substance when given the mass and volume we use the formula
[tex]density = \frac{mass}{volume} [/tex]
From the question
mass = 15 g
volume of rock = 5 cm³
The density of the substance is
[tex]density = \frac{15}{5} [/tex]
We have the final answer as
3.0 g/cm³
