First, write the chemical reaction:


"\\text{ Fe}+\\text{S}\u2192\\text{FeS}."

This reaction occurs with heat, and it shows that the amount of substance for iron is the same as the amount of substance for sulfur. Find the amount of substance for sulfur:


"n_S=\\frac{m_S}{M_S}=\\frac{16}{32}=0.5\\text{ mol}."

Find the mass of iron:


"m_I=n_IM_I=n_SM_I=0.5\u00b756=28\\text{ g}."
