Chapter 2, Problem 2.35P

Interpretation Introduction

Interpretation:Atomic mass of magnesium is to be calculated.

Concept introduction:Atomic mass of element depends on abundance of its isotopes that occur naturally and their isotopic mass.

Formula to calculate atomic mass of an element is as follows:

  $\text{Atomic}\text{mass}\text{of}\text{an}\text{element}=\frac{{\displaystyle \sum \left(\begin{array}{l}\left(\text{Isotopic}\text{mass}\text{of}\text{an}\text{element}\right)\\ \left(\text{abundance of that}\text{isotope}\text{in}\text{\%}\right)\end{array}\right)}}{100}$
