Question

An aluminum engine block has a volume of 4.77 L and a mass of 12.88 kg. what is the density of the aluminum in grams per cubic centimeter

Answer 1

`1l=1dm^(3)=10cm*10cm*10cm=1000cm^(3)`
This means that the volume of block is :

`V=4,77*1000cm^(3)=4770cm^(3)`


`1kg=1000g`
This means that the mass of block is:

`M=12,88*1000g=12880g`
The density of the aluminum can be counted with equation:

`ς=(M)/(V)=(12880)/(4770)=2,7(g)/(cm^(3))`
