Calculate the percentage of the naturally occurring isotopes `.^(35)Cl and .^(37)Cl` that accounts for the atomic mass of chlorine taken as 35.45.

Explanation

To calculate the percentage of the naturally occurring isotopes \(^{35}\text{Cl}\) and \(^{37}\text{Cl}\) that accounts for the atomic mass of chlorine taken as 35.45, we can follow these steps:

### Step-by-Step Solution:

1. **Define Variables**:
- Let \( x \) be the percentage of \(^{35}\text{Cl}\).
- Then, the percentage of \(^{37}\text{Cl}\) will be \( 100 - x \).
