Answer:

a. Número de átomos de S = 1.41 × 10^23 atoms

b. Número de átomos de Fe = 1.37 × 10^24 atoms

Explanation:

Dados los siguientes parámetros;

Masa de Sulphur, S = 7.5g

Masa de Iron, Fe = 125g

a. Para determinar el número de átomos en 7.5g de S;

Masa molar de S = 32

Para encontrar el número de lunares;

Numero \; de \; lunares = \frac {Masa}{Masa \; molar}

Sustituyendo en la ecuación, tenemos;

Numero \; de \; lunares = \frac {7.5}{32}

Numero de lunares = 0.2344 lunares.

Sabemos que la constante de Avogadro es igual a 6.02 * 10^23 mol¯¹

Número de átomos de S = Numero de lunares de S * Avogadro constant

Sustituyendo en la ecuación, tenemos;

Número de átomos de S = 0.2344 × 6.02 * 10^23

<em>Número de átomos de S = 1.41 × 10^23 atoms</em>

b. Para determinar el número de átomos en 125g de Fe;

Masa molar de Fe = 55

Para encontrar el número de lunares;

Numero \; de \; lunares = \frac {Masa}{Masa \; molar}

Sustituyendo en la ecuación, tenemos;

Numero \; de \; lunares = \frac {125}{55}

Numero de lunares = 2.2727 lunares.

Sabemos que la constante de Avogadro es igual a 6.02 * 10^23 mol¯¹

Número de átomos de Fe = Numero de lunares de Fe * Avogadro constant

Sustituyendo en la ecuación, tenemos;

Número de átomos de Fe = 2.2727 × 6.02 * 10^23

<em>Número de átomos de Fe = 1.37 × 10^24 atoms</em>

How does the author foreshadow Arachne’s fate through her characterization?
Alchen [17]
     Arachne is a weaver that boasts she is the best weaver in the universe and that no one can match her skills. This comes back to bite her later when she is put in a cloth making competition with Athena. Arachne, of course, loses and is turned into a spider. 
     Arachne's characterization foreshadows her fate by her being boastful.
