Question

16. The density of a substance is 2.7 g/cm3. What will be the volume of 1350 g of that substance? (solve the numerical stepwise)​

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
