Answer:

3g/cm3

Step-by-step explanation:

The density equation is M over V so you divide the mass by the volume. You do 21 divided by 7 and you get 3

Answer:

3 g/cm³

Step-by-step explanation:

The density of a substance can be found by using the formula


density = (mass)/(volume) \\

From the question

mass = 21 g

volume = 7 cm³

We have


density = (21)/(7) = 3 \\

We have the final answer as

3 g/cm³

Hope this helps you
