Chapter 3, Problem 3.6P

(a)

Interpretation Introduction

Interpretation:Whether the element left, right or neither has higher molar mass should be identified.

Concept introduction:Atomic mass expressed in $\text{amu}$ is numerically equivalent to mass of $\text{1 mole}$ of atoms in grams. One mole of any substance possesses Avogadro number of particles or ions or species equivalent to $6.022\times {10}^{23}$ .

Chemists use molecular weight and molar masses of compounds to determine the stoichiometric quantities such as moles, molarity, molality that are useful to determine the number of reactant or products involved in a certain reaction.

(b)

Interpretation Introduction

Interpretation: Whether the element left, right or neither has more atoms per gram should be identified.

(c)

Interpretation Introduction

Interpretation: Whether the element left, right or neither has fewer atoms per gram should be identified.
