Using these data, we have estimated the HI masses, the H$_2$ masses and the dust masses. We find that for far-infrared selected galaxies: (1) the median value of M$_{H2}$/M$_{HI}$ is 0.5, meaning that the atomic phase dominates in these galaxies. The fraction of gas in molecular form increases with increasing FIR luminosity but does not show any obvious trend with other galaxy properties.
