Table 3:
Calculations of the ratios of trapped masses of volatiles to the mass of
H2O ice in planetesimals formed at 9.8 and 12 AU in the solar nebula. Gas-phase abundance of H2O is equal to
(4.9 times the value quoted in Table 2; see text), and gas-phase abundances of elements are assumed to be solar (Lodders 2003) with CO2:CO:CH4 = 30:10:1 and with N2:NH3 = 1 in vapor phase in the solar nebula.
The abundance of H2S is subsolar (see text).
