Nitrogen occurs in nature in the form of two isotopes with atomic mass 14 and 15 respectively. If average atomic mass of nitrogen is 14.0067, what is the % abundabce of the two isotopes ?

Explanation

To find the percent abundance of the two isotopes of nitrogen (Nitrogen-14 and Nitrogen-15) given their atomic masses and the average atomic mass of nitrogen, we can follow these steps:

### Step-by-Step Solution:

1. **Define Variables:**
Let the percent abundance of Nitrogen-14 be \( X \). Therefore, the percent abundance of Nitrogen-15 will be \( 100 - X \).

2. **Set Up the Equation:**
