Answer: The moles of 15.0 g of Fe is 0.2685 moles.

Explanation:

To calculate the number of moles, we use the formula:

[tex]Moles=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]

We are given:

Mass of Iron = 15 g

Molar mass of iron = 55.85 g/mol

Putting the values in above equation, we get:

[tex]\text{moles of iron}=\frac{15g}{55.85g/mol}=0.2685moles[/tex]

Hence, the moles of 15.0 g of Fe is 0.2685 moles.
