Question

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?

a.5.2 g/cm3
b.5.9 g/cm3
c.6.4 g/cm3
d.7.0 g/cm3

Answer 1

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


`D = (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 = (m)/(V)= (82.0g)/(12.8cm^(3) ) = 6.4g/ cm^(3)`

The answer is then letter C.
