Hello!
To find the density of any object, we will need to use the formula: d = m/V.
In this formula, d is the density, m is the mass and V is the volume.
We are given the volume and mass. The volume is 12 cubic centimeters and the mass is 32 grams. With these values, we can find the density using the formula.
d = 32 grams / 12 cm³
d = 8/3 grams/cm³
d ≈ 2.67 g/cm³
Therefore, it's density is equal to about 2.67 g/cm³.
<span>With any element, there are a range of isotopes . . . a weighted average mass is used because there exist different isotopes of that element, each of varying mass. A weighted average accounts for the fact that the average mass (that may likely be measured from a random sample of the element) will most likely reflect the average mass of the more abundant isotopes. So the weighted average mass will be most comparable to the more abundant isotopes.</span>
