# The density of a sample of aluminum is 2.70 g/cm3. You submerse a sample of aluminum in water, and the volume of the water rises 1.3 L (1.3 L is displaced by the aluminum). Using the correct number of significant figures, what is the mass of the sample?

##### 1 Answer

The mass of aluminum is 3500 g, rounded to two significant figures.

#### Explanation:

Density is mass per unit of volume.

The displaced volume of water is the volume of the aluminum sample.

Since the given density is in

In order to determine the mass of an object when its density and volume are known, the equation needs to be rearranged to isolate

Substitute the given density and volume into the equation and solve.
