Question

Calculate the following:
the number of moles in 15.0 g of Fe

Answer 1

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

Explanation:

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

`Moles=\frac{\text{Given mass}}{\text{Molar mass}}`

We are given:

Mass of Iron = 15 g

Molar mass of iron = 55.85 g/mol

Putting the values in above equation, we get:

`\text{moles of iron}=(15g)/(55.85g/mol)=0.2685moles`

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