5. Aluminum has a density of 2.70 g/ cm3. What volume is occupied by a block of aluminum which weighs 4.32 kg?

To solve this problem, we can use the formula:

Density = Mass/Volume

First, let's convert the mass of the aluminum block to grams:
4.32 kg * 1000 g/kg = 4320 g

Now, we can rearrange the formula to solve for the volume:
Volume = Mass/Density

Volume = 4320 g / 2.70 g/cm^3

Dividing the mass by the density, we get:

Volume = 1600 cm^3

Therefore, the volume occupied by the block of aluminum is 1600 cm^3.
