The nuclear mass of `._26F^(56)` is 55.85u. Calculate its nuclear density.

Explanation

To calculate the nuclear density of the isotope \( _{26}^{56}Fe \), we can follow these steps:

### Step 1: Identify the Given Data
We are given:
- Nuclear mass of Iron (Fe) = 55.85 u
- Mass number (A) = 56

### Step 2: Convert the Nuclear Mass from Atomic Mass Units (u) to Kilograms
