Two nuclei have mass numbers in the ratio 2:5. What is the ratio of their nuclear densities?

Explanation

To find the ratio of nuclear densities of two nuclei with mass numbers in the ratio of 2:5, we can follow these steps:

### Step 1: Define Mass Numbers
Let the mass numbers of the two nuclei be:
- \( A_1 = 2 \) (for the first nucleus)
- \( A_2 = 5 \) (for the second nucleus)

### Step 2: Understand Nuclear Density
