Question

Solve the following problem showing all work, the formula, and correct units.

Answer 1

5g/cm³

it is not iron.

Explanation:

Given parameters:

Density of iron = 7.874g/cm³

Mass of metal = 2000g

Volume of metal = 400cm³

Unknown:

Density of bar = ?

Is it iron = ?

Solution:

The density of a substance is its mass per unit area. Every substance have an intensive density value that typifies them all.

The density of water and other substances are the same if they maintain their level of pureness.

   Density = $\frac{mass }{volume}$

Density of metal bar = $\frac{2000}{400}$ = 5g/cm³

Since this value is not the same as the given density of iron, it is not iron.
