Calculate the percentage of :
Aluminium
in sodium aluminium fluoride `[Na_(3)AlF_(6)]` , to the nearest whole number. (Atomic Mass : Na = 23, Al = 27, F = 19]

Explanation

To calculate the percentage of Aluminium in sodium aluminium fluoride (Na₃AlF₆), we will follow these steps:

### Step 1: Identify the molecular formula and the atomic masses
The molecular formula of sodium aluminium fluoride is Na₃AlF₆. We have the following atomic masses:
- Sodium (Na) = 23 g/mol
- Aluminium (Al) = 27 g/mol
- Fluorine (F) = 19 g/mol
