Question

Aluminum has a density of 2.7 g/mL chemical or physical change

Answer 1

Explanation:

The density of a substance tells you the mass of exactly one unit of volume of said substance.

In your case, aluminium is said to have a density of

density Al

=

2.70 g

.

cm

−

3

This tells you that every

1 mL

of aluminium has a mass of

2.70 g

.

All you have to do now is use the density of aluminium as a conversion factor to go from cubic centimenters of aluminium to grams

Answer 2

Aluminum has a density of 2.7 g/mL It is a physical change

Explanation:

• The density of a substance is the mass per unit volume
• Aluminum has a density of 2.7 g/mL
• It implies that Aluminium has 2.7 g per ml
• It is a unique property of a substance

Density =m/V

where m is the mass of the substances and v is the volume of solute.

• It is a property how an object takes up in relation to the matter.
