For this problem, to determine the number of moles given the number of molecules, we use the Avogadro's number. This is an empirical value that relates the number of particles (e.g. atoms, molecules, sub-particles) in one mole of any substance. The value is 6.022×10²³ molecules/mol.
5.080×10¹⁶ molecules * 1 mol/6.022×10²³ molecules = <em>8.436×10⁻⁸ moles of hydrogen</em>
