Calculate the atomic mass of chlorine, which consists of 76% of all the chlorine in nature, and chlorine - 37 that makes up the other 24%.

Explanation

To calculate the atomic mass of chlorine, which consists of two isotopes, chlorine-35 and chlorine-37, we will follow these steps:

### Step 1: Identify the isotopes and their percentages
- Chlorine-35 (Cl-35) makes up 76% of natural chlorine.
- Chlorine-37 (Cl-37) makes up 24% of natural chlorine.

### Step 2: Use the formula for average atomic mass
The average atomic mass can be calculated using the formula:
