\caption{Calculations of the ratios of trapped masses of volatiles to the mass of 
H$_2$O ice in planetesimals formed at 9.8 and 12 AU in the solar nebula. Gas-phase abundance of H$_2$O is equal to $8.11 \times 10^{-4}$ ($\sim$4.9 times the value quoted in Table~\ref{table_L03}; see text), and gas-phase abundances of elements are assumed to be solar (Lodders \cite{Lodders03}) with CO$_2$:CO:CH$_4$~=~30:10:1 and with N$_2$:NH$_3$~=~1 in vapor phase in the solar nebula. 
The abundance of H$_2$S is subsolar (see text).}
