Question

The density of aluminum is 2.7 g/mL. If the mass of this piece of aluminum is 244 grams, what is the volume of the aluminum? D = M / V

Round to the nearest tenth.

Answer 1

Answer:

2.70 gram

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

10.0

⋅

2.70 g
