    You have a lousy equation. All pluses. No arrow. No way to tell which are the reactants and which the products. I'll leave that for you to correct but here is how you work the problem (in general terms).
    1. Write and balance a good equation.
    2. Convert 50 g Fe to moles. moles = grams/molar mass.'
    3. Using the coefficients in the balanced equation, convert moles Fe to moles H2S.
    4. Now convert moles H2S to grams. g = moles x molar mass.
