Calculate the energy in joules required to convert all the atoms of sodium to sodium ions present in 2.3 mg of sodium vapours? Ionization enthalpy of sodium is `495 kJ "mol"^(-1 )` (Atomic mass of Na = 23)

Explanation

To calculate the energy required to convert all the atoms of sodium in 2.3 mg of sodium vapors to sodium ions, we will follow these steps:

### Step 1: Convert the mass of sodium to moles
We know the atomic mass of sodium (Na) is 23 g/mol. First, we need to convert the mass of sodium from milligrams to grams.

\[ \text{Mass of sodium} = 2.3 \, \text{mg} = \frac{2.3}{1000} \, \text{g} = 0.0023 \, \text{g} \]
