considering the shape of a Ca nucleus like a sphere, calculate the density of the nucleus of Ca of mass number 40

Explanation

To calculate the density of the nucleus of calcium (Ca) with a mass number of 40, we will follow these steps:

### Step 1: Understand the Formula for Density
Density (ρ) is defined as the mass (m) of an object divided by its volume (V):
\[ \rho = \frac{m}{V} \]
