    Answer:

    1.43 grams

    Explanation:

    Fe = 55.8 grams Fe = 1 mole Fe

    2.56 • 10^-3 moles Fe / 1 • 55.8 grams Fe / 1 mole Fe = 1.43 grams Fe

    Basically, you’re just multiplying the molar mass of Fe (iron) by the moles of 2.56 • 10^-3 Fe, to find how many grams are in it.

    2.56 • 10^-3 moles Fe = 1.43 grams Fe
