Open clusters provide a controlled setting to investigate the interplay between mass and metallicity on a more localized level. However, the specific analysis of this relation within individual open clusters has been sparsely investigated, despite its significance. In this study, we aim to fill this research gap by conducting a comprehensive analysis of 75-star clusters, with the objective of examining the trends and probing the underlying mechanisms governing their mass-metallicity relationship.
