Answer 1

To find out how many moles are in 223.2 g of iron (Fe), we can use the formula moles = mass (g) / molar mass (g/mol). Substituting the given values, we find that there are 4 moles in 223.2 g of iron (Fe).

Step-by-step explanation:

The question asks how many moles are in 223.2 g of iron (Fe). To determine the number of moles, we need to use the molar mass of iron. The molar mass of iron is 55.8 g/mol. We can use the formula:

moles = mass (g) / molar mass (g/mol)

Substituting the given values, we have:

moles = 223.2 g / 55.8 g/mol = 4 moles

Therefore, there are 4 moles in 223.2 g of iron (Fe).
