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 \→ 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.
