Molar Mass of AgI: A Comprehensive Guide to Understanding Its Properties and Applications

Introduction

The molar mass is a fundamental property of any substance that quantifies its mass per mole. It plays a crucial role in various chemical and physical calculations. For silver iodide (AgI), a light-sensitive material used in photography and other applications, understanding its molar mass is essential. This guide delves into the molar mass of AgI, its significance, and its practical applications.

Definition and Calculation of Molar Mass

The molar mass of a substance is the mass of one mole of that substance. It is expressed in grams per mole (g/mol) and is calculated as the sum of the atomic masses of all the elements present in the molecule. For AgI, the molar mass can be calculated as follows:

Molar Mass = (Atomic mass of Ag) + (Atomic mass of I)
= 107.87 g/mol + 126.90 g/mol
= 234.77 g/mol

Therefore, the molar mass of AgI is 234.77 g/mol. This means that one mole of AgI weighs 234.77 grams.
