Question

A block of aluminum occupies a volume of 15.0 mL and weighs 40.5 g. What is its density?

Answer 1

Explanation:

Usually, density will have units of g/ml

when dealing with a liquid or units of

g/cm^3 when dealing with a solid.

• The mass has units of grams, g

.

• The volume will have units of mL or cm^3

We are given the mass and the volume, both of which have good units, so all we have to do is plug the given values into the equation:

Density=40.5g/15.0mL

Thus, the block of aluminum has a density of 2.70 g/mL.
