An aluminum block has a mass of 82.0 g and a volume of 12.8 cm3. what is the block's density to the nearest g/cm3?

aksik [14]

Density is mass over volume. If you put it into a formula it would look like this:

$D = \frac{m}{v}$

Based on the problem given, you can see that the mass of the aluminum block is 82.0 g and the volume is 12.8 cm3. Just put that into your equation and solve for it:

$D = \frac{m}{V}= \frac{82.0g}{12.8cm^{3} } = 6.4g/ cm^{3}$

The answer is then letter C.
