    Start by writing the balanced equation, and deduce the ratio that iron and sulfur react in.
    Then working out how many moles you have of each. The limiting substance is the one that isn't in excess.

    Then work out what the maximum number of moles of FeS you could obtain. What is the mass of that many moles?
