    Answer:

    98.8g (3 s.f.)

    Explanation:

    Use the mole = mass/mr equation to find the moles of CaO, then use the molar ratio to find the moles of Fe2O3, which is the same as CaO, (assuming the ratio is 1:1, as you haven’t stated it clearly in the question). Then use the equation and input to find Mass, which is 98.8g to 3 s.f.
