  "abstract": "Mass is among the most fundamental properties describing a galaxy. The relation between the luminosity and the total mass of a galaxy contains information on the efficiency of the star formation process and on the distribution of dark matter. We used strong gravitational lensing data from the Euclid Quick Data Release 1 (Q1) to constrain the total mass enclosed within an aperture of $5\\,h^{-1}$kpc, $M_5$, of elliptical galaxies. Our analysis is based on a sample of 95 lenses, which we built by ensuring that their selection function is reproducible. This enabled us to correct our inference for selection effects. The average $\\log_{10}{(M_5\\,h\\,M_\\odot^{-1})}$ for a galaxy with an $r$-band luminosity of $10^{10.7}L_{\\odot}\\,h^{-2}$ at $z=0.5$ is $11.30\\pm0.02$. The mass $M_5$ scales with luminosity to the power $β_\\mathrm{L}=0.71\\pm0.07$, and decreases with increasing redshift at fixed luminosity. Assuming a scenario in which galaxies grow by mergers and stellar populations evolve passively, these correlations imply that $M_5$ increases with time for individual galaxies. These measurements provide a useful benchmark for testing models of galaxy structure and evolution that make predictions on the distribution of total mass on the scales of $5\\,h^{-1}$kpc.",
