Chapter 3, Problem 111AE

Interpretation Introduction

Interpretation: The atomic weight of $\text{X}$ in the compound ${\text{XI}}_{\text{2}}$ is to be predicted.

Concept introduction: An element’s atomic weight establishes numerical relation among various elements. Any element’s isotope possesses its characteristic atomic weight. Atomic weight is basically the number denoting the total nucleons (neutrons and protons) that acquire an element. The knowledge about every elements’ atomic mass is quite important in estimating any compound’s molar mass.
