Use the following expression, no.1 e-4/2kT %3D n2 to calculate the ratio of H atoms to H2 molecules in a hydrogen gas in thermal equilibrium with a reservoir at 904 K when there are 6 x 1020 molecules m3 of H2. Recall that A = 4 eV and that a convenient approximation for the quantum density is given by no= (1030 m-3)(m/m3/2(T/300 K)3/2, where the value of the temperature in K must be inserted for T, and the ratio of m/m, is the atomic mass (in atomic mass units, amu) for an atom, or the sum of atomic masses (in amu) for atoms in a molecule. Write the numerical answer in exponential form accurate to 2 decimal places, as described in the worksheet instructions (X.XXE+Y or X.XXE-Y).
