We study B → η' Xₛ within the framework of the Standard Model. Several mechanisms such as b → η' s g from the QCD anomaly, and b → η's and B→ η' s q from four-quark operators are treated simultaneously. We find that the first mechanism give a significant contribution to the branching ratio for B→ η' Xₛ, while the other two mechanisms account for about 15% of the experimental value. The Standard Model prediction for B→ η' Xₛ is consistent with the CLEO data.
