Two nuclei have mass number in the ratio 1:2. What is the ratio of their nuclear densities?

Explanation

To solve the problem of finding the ratio of nuclear densities of two nuclei with mass numbers in the ratio of 1:2, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Nuclear Density**:
The nuclear density (ρ) is defined as the mass (m) of the nucleus divided by its volume (V). The formula for density is:
\[
\rho = \frac{m}{V}
