There are two isotopes of an element with atomic mass z. Heavier one has atomic mass z+2 and lighter one has z-1, then abundance of lighter one is

Text Solution

AI Generated Solution

To find the abundance of the lighter isotope, we can follow these steps: ### Step 1: Define Variables Let: - The percentage abundance of the heavier isotope (atomic mass \( z + 2 \)) be \( x \). - The percentage abundance of the lighter isotope (atomic mass \( z - 1 \)) be \( 100 - x \). ### Step 2: Set Up the Equation ...
