INTRODUCTION OF AVG. ATOMIC MASS
Average Atomic Mass: The average atomic mass of an element is the weighted average of the masses of the naturally occurring isotopes of that element. It's a way to represent the average mass of an atom of a given element, taking into account the varying masses of its isotopes. Formula: Average Atomic Mass = (Mass of Isotope 1 x Abundance of Isotope 1) + (Mass of Isotope 2 x Abundance of Isotope 2) + ... Example: For example, the average atomic mass of carbon is 12.01 u (unified atomic mass units), which is a weighted average of the masses of its two naturally occurring isotopes: carbon-12 (mass: 12 u, abundance: 98.9%) and carbon-13 (mass: 13 u, abundance: 1.1%).
