The atomic mass of `F^(19)` is 18.9984 `m_(u)`. If the masses of proton and neutron are `1.0078 m_(u)` and `.0087 m_(u)`. Respectively, calculate the binding energy per nucleon (ignore the mass of electrons). `(1 m_(u) = 931) MeV)`

Explanation

To solve the problem of calculating the binding energy per nucleon for fluorine-19 (\(F^{19}\)), we will follow these steps:

### Step 1: Determine the number of protons and neutrons
The atomic number of fluorine is 9, which means it has 9 protons. The mass number of fluorine-19 is 19, which means it has:
- Number of neutrons = Mass number - Number of protons
- Number of neutrons = 19 - 9 = 10

### Step 2: Calculate the total mass of protons and neutrons
