Most of the mass, most of the baryons, and most of the galaxies in the Universe are in galaxy groups. The processes connecting cooling gas in the hot inter- galactic medium and feedback from AGN are more easily observed in groups than in clusters because of their shallower potential wells. A precise characterization of the X-ray luminosity-mass relation over a large mass range is today's single most important task to ensure that the full cosmological power from the 100000 groups and clusters to be detected with eROSITA can be exploited. We will use a complete sample of almost 90 galaxy groups and clusters to constrain cooling and feedback mechanisms as well as the Lx-M relation. Observations for all clusters are available. With this short proposal we aim to complete observations for the group sample.
