Question

The density of iron is 7.8 g/cm^3 (cubed), what is the mass of 5 cm^3 (cubed) of it? Include the symbol for the correct unit.

Answer 1

The answer is 39 g

Step-by-step explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume of iron = 5 cm³

density = 7.8 g/cm³

It's mass is

mass = 5 × 7.8

We have the final answer as

39 g
