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

Explanation

To calculate the nuclear density of fluorine-56 (represented as \( _{26}^{56}F \)), we will follow these steps:

### Step 1: Convert Nuclear Mass to Kilograms
The nuclear mass of fluorine-56 is given as 55.85 u. We need to convert this mass into kilograms. The conversion factor from atomic mass units (u) to kilograms is approximately \( 1 \, \text{u} = 1.66 \times 10^{-27} \, \text{kg} \).

\[ \text{Mass in kg} = 55.85 \, \text{u} \times 1.66 \times 10^{-27} \, \text{kg/u} \]
