Answer to Problem 18E
The graph for the nuclear radius versus mass number is,
Explanation of Solution
From part (a) the nuclei radii for
The below figure (1) shows the graph for the nuclear radius versus mass number,
This graph shows a straight line except for the lighter nuclei. This indicates that the volume is proportional to the mass of the nuclei. And the density is almost constant for the nuclei.
Conclusion:
The graph for the nuclear radius versus mass number is,
