On analysing an impure sample of sodium chloride, the percentage of chlorine was found to be 45.5. What is the percentage of pure sodium chloride in the sample ?

Explanation

To find the percentage of pure sodium chloride (NaCl) in the sample based on the percentage of chlorine (Cl) found, we can follow these steps:

### Step 1: Understand the Composition of Sodium Chloride
Sodium chloride (NaCl) consists of sodium (Na) and chlorine (Cl). The molar mass of NaCl is approximately 58.5 g/mol, where:
- Sodium (Na) has a molar mass of about 23 g/mol.
- Chlorine (Cl) has a molar mass of about 35.5 g/mol.

### Step 2: Calculate the Percentage of Chlorine in Pure Sodium Chloride
