WebFormic acid is a promising hydrogen carrier owing to its high hydrogen density and liquid phase. Therefore, the production of hydrogen from formic acid via catalytic dehydrogenation reaction has been extensively studied. Various methods such as alloying of the active Pd metal with other metals and adding dopants (e.g., the amine-functional … WebExplain why. a) As each mole consists of same number of atoms or molecules i.e. (6.022 ×10^23) , therefore one mole of H2, one mole of O2 and one mole of F2 have same number of molecules. b) Mass of 1 mole of substance is known as its molar mass. Thus , mass of 1 mole of H2 = 2× (1.0 g/mol) = 2.0 g/mol.
