The percent abundance of the post-1982 pennies is 56%.
<h3>What is percent abundance?</h3>
Percent abundance is the percentage amount of all naturally occurring isotopes of an element.
<h3> Percent abundance of the post-1982 pennies</h3>
The percent abundance of the post-1982 pennies is calculated as follows;
percent abundance = number of post-1982 pennies / total number of pennies x 100%
percent abundance = (28) / (50) x 100%
percent abundance = 56%
Thus, the percent abundance of the post-1982 pennies is 56%.

Answer:
10.69g/cm^3 or 0.0106kg/m^3
Explanation:
10.69 g/cm^3: I wrote this answer because your question doesn't mention whether volume is in cm^3 or m^3. If its in cm^3, then this is your answer.
0.0106kg/m^3: This might also be the answer if the volume is in m^3. If it is in m^3 then you have convert grams into kilograms.
So technically since you questions incomplete, the equation for measuring density is P= m/v
P= rho (density)
m= mass
v= volume
