Chapter 2, Problem 2.79P

a)

Interpretation Introduction

Interpretation:Formula, name and molecular mass of the below mentioned molecules should be written.

  

Concept introduction:In the molecular formula, the exact number and type of constituent atoms are shown. Type of constituent atoms is represented by their atomic symbols and number of each constituent atom is represented in the right subscript of its atomic symbol. In a hypothetical molecule ${\text{A}}_{\text{x}}{\text{B}}_{\text{y}}$ , x number of $\text{A}$ atom and y number of $\text{B}$ atom combines to form the compound.

Formula to calculate molecular mass of ${\text{A}}_{\text{x}}{\text{B}}_{\text{y}}$ is as follows:

  $\text{Molecular}\text{mass}\text{of}{\text{A}}_{\text{x}}{\text{B}}_{\text{y}}\text{=}\left(\begin{array}{l}\left(\text{x}\right)\left(\text{Atomic}\text{mass}\text{of}\text{A}\right)\text{+}\\ \left(\text{y}\right)\left(\text{Atomic}\text{mass}\text{of}\text{B}\right)\end{array}\right)$
