<u>Answer:</u>
Lead
<u>Explanation:</u>
To get the density of the material, the formula would be:
mass divided by volume which is given by
.
Here in this problem, we are given a mass of
which occupies a volume of
.
So plugging the data in the above formula to find the density:
Density =
From the table, we can see that the material is Lead which has a density of 11.3c/cm^3.
