Question

(ii) The density of aluminium is 2.7 g/cm^3. Find the mass of a
block of aluminium if its volume is 150 cm^3.
​

Answer 1

Answer:

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

150cm3. 2.7/1cm3=405
