Chapter 6, Problem 6.27EP

(a)

Interpretation Introduction

Interpretation:

The conversion factor that is required for conversion of moles of $H_{3}P{O}_4$ to moles of $H$ atoms has to be written based on the chemical formula $H_{3}P{O}_4$.

Concept Introduction:

Chemical formula of a substance can be interpreted in two different ways, namely, in microscopic-level and macroscopic-level.  Chemical formula at microscopic-level can be said as the one that indicates the number of atoms of different elements that is present in a formula unit or one molecule of substance.  The numerical value present in subscripts in a chemical formula indicates the number of atoms of various elements that is present in one formula unit of substance.

In macroscopic-level the chemical formula of a substance indicates the number of moles of atoms of different elements that is present in one mole of a substance.

Conversion factors which relate a component of a substance to the substance as a whole are dependent on the chemical formula of the substance.

Interpretation Introduction

Interpretation:

The conversion factor that is required for conversion of moles of $H_{3}P{O}_4$ to total moles of atoms has to be written based on the chemical formula $H_{3}P{O}_4$.
