### 392.4 g

Explicar

## Step1: Determine the molar mass of Zinc<br />### The molar mass of Zinc (Zn) is approximately 65.38 g/mol.<br />## Step2: Calculate the number of moles<br />### Use Avogadro's number, $6.022 \times 10^{23}$ atoms/mol, to find the number of moles: $\frac{3.6 \times 10^{24}}{6.022 \times 10^{23}} \approx 5.98$ moles.<br />## Step3: Calculate the mass<br />### Multiply the number of moles by the molar mass: $5.98 \text{ moles} \times 65.38 \text{ g/mol} \approx 391.77 \text{ g}$.
