Calculate the atomic mass of antimony using the weight average mass method. Concept introduction: ► Isotopes: The atoms of an element with different mass number or atomic mass are called isotopes. They have same number of protons and electrons but different number of neutrons. Therefore, it is not necessary that all atoms of a given element contain the same number of neutrons in their nuclei. For example, hydrogen has three isotopes H 1 , H 2 ,H 3 with 0, 1 and 2 neutrons in their nuclei respectively. Given: Isotope Mass (amu) Abundance (%) Sb-121 120.90 57.21 Sb-123 122.90 42.79

Question

Chapter 4, Problem 4.128CQ

Interpretation Introduction

Interpretation:

Calculate the atomic mass of antimony using the weight average mass method.

Concept introduction:

► Isotopes: The atoms of an element with different mass number or atomic mass are called isotopes. They have same number of protons and electrons but different number of neutrons. Therefore, it is not necessary that all atoms of a given element contain the same number of neutrons in their nuclei. For example, hydrogen has three isotopes $H^{1} {, H}^{2} {,H}^{3}$ with 0, 1 and 2 neutrons in their nuclei respectively.

Given:

Isotope Mass (amu) Abundance (%)
