Answer:
12g
Explanation:
Given parameters:
Volume of rock = 4.0cm³
Density of rock = 3.0g/cm³
Unknown:
Mass of the rock = ?
Solution:
Density is the mass per unit volume of a substance.
Mathematically, it is expressed as;
Density = [tex]\frac{mass}{volume}[/tex]
Mass = density x volume
Now, insert the parameters and solve;
Mass = 3.0g/cm³ x 4.0cm³ = 12g
