Just more than 25% of its mass is hydrogen, and it has a density just under 500 kg/m^3 at 70 K, for a total of 1.75 tonnes hydrogen per dton. It should also be extremely common on outer system bodies. At liquid hydrogen temperatures, its density is slightly greater at 520 kg/m^3, for a total of 1.83 tonnes hydrogen per dton. - Tim
