For every one `""^37Cl` isotopes there are three `""^35Cl` isotopes in a sample of chlorine. What will be the average atomic mass of chlorine?

Options

A. 35
B. 37
C. 35.5
D. 35.6

Explanation

To find the average atomic mass of chlorine in the given sample, we can follow these steps:

### Step 1: Identify the number of isotopes
In the sample, we have:
- 3 isotopes of Chlorine-35 (denoted as \(^{35}\text{Cl}\))
- 1 isotope of Chlorine-37 (denoted as \(^{37}\text{Cl}\))

### Step 2: Calculate the total mass contributed by each isotope
