Chapter 6, Problem 6.24EP

(a)

Interpretation Introduction

Interpretation:

Total moles of atoms that is present in $3.00mole$ of $S_2{N}_2$ has to be calculated.

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.

(b)

Interpretation Introduction

Interpretation:

Total moles of atoms that is present in $3.00mole$ of $S_4{N}_4$ has to be calculated.
