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.
