  The thermodynamic properties of the superconducting state induced in metallic
molecular hydrogen under the influence of pressure 347 GPa were determined. In
particular, it has been shown that the critical temperature ($T_{C}$) changes
in the range from 120 K to 90 K for $\mu^{*}\in<0.08,0.15>$, where $\mu^{*}$ is
the value of the Coulomb pseudopotential. Next, the energy gap near the
temperature of zero Kelvin ($2\Delta(0)$) was calculated. It has been stated,
that the dimensionless ratio $2\Delta(0)/k_{B}T_{C}$ slightly decreases with
the increase of $\mu^{*}$ from 3.98 to 3.84. In the last step, the ratio of
effective electron mass ($m^{*}_{e}$) to the bare electron mass ($m_{e}$)) was
determined. It has been proved that $m^{*}_{e}/m_{e}$ takes its highest value
equal to 1.96 for $T=T_{C}$.
