Question

Chapter U4, Problem C14.5RE

Interpretation Introduction

Interpretation: The following compounds should be listed in increasing order of moles of metal:

$5.0 g NaCl, 5.0 g AgCl, 5.0 g LiCl$

Concept Introduction: The mathematical relationship between number of moles, mass of substance and molar mass is:

$number of moles = mass of the substanceMolar mass of the substance$ - (1)

Expert Solution & Answer

Answer to Problem C14.5RE

$AgCl<NaCl<LiCl$ .

Explanation of Solution

The given compounds are:

$5.0 g NaCl, 5.0 g AgCl, 5.0 g LiCl$

The number of moles of each compound is determined using equation (1) as:

For

$5.0 g NaCl$ :

The molar mass of $NaCl$ is $58.44 g/mol$ .

Substituting the values:

$number of moles = 5.0 g58.44 g/molnumber of moles = 0.086 mol$

Since, 1 mole of $NaCl$ contains 1 mole of $Na+$ metal so, $0.086 mol$ of $NaCl$ will contain $0.086 mol$ of $Na+$ metal.

For

$5.0 g AgCl$ :

The molar mass of $AgCl$ is $143.32 g/mol$ .

Substituting the values:

$number of moles = 5.0 g143.32 g/molnumber of moles = 0.035 mol$

Since, 1 mole of $AgCl$ contains 1 mole of $Ag+$ metal so, $0.035 mol$ of $AgCl$ will contain $0.035 mol$ of $Ag+$ metal.

For

$5.0 g LiCl$ :

The molar mass of $LiCl$ is $42.394 g/mol$ .

Substituting the values:

$number of moles = 5.0 g42.394 g/molnumber of moles = 0.118 mol$

Since, 1 mole of $LiCl$ contains 1 mole of $Li+$ metal so, $0.118 mol$ of $LiCl$ will contain $0.118 mol$ of $Li+$ metal.

Thus, the given compounds can be listed in increasing moles of metal in each compound as:

$AgCl<NaCl<LiCl$
