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 :

[tex]1l=1dm^{3}=10cm*10cm*10cm=1000cm^{3}[/tex]
This means that the volume of block is :
[tex]V=4,77*1000cm^{3}=4770cm^{3}[/tex]

[tex]1kg=1000g[/tex]
This means that the mass of block is:
[tex]M=12,88*1000g=12880g[/tex]
The density of the aluminum can be counted with equation:
[tex]ς=\frac{M}{V}=\frac{12880}{4770}=2,7\frac{g}{cm^{3}}[/tex]
