Elements emit colours when heated because electrons in atoms can have only certain allowed energies.Heating an atom excites its electrons and they jump to higher energy levels. When the electrons return to lower energy levels, they emit energy in the form of light. Every element has a different number of electrons and a different set of energy levels. Thus, each element emits its own set of colours. See, for example, mercury and neon above. Those colours are as distinctive to each element as fingerprints are to people.
Lol. Here I am.. Saying whatever the heck I want. :)

There are 252.07 grams of ammonium dichromate per mol of ammonium dichromate molecules. There are 8 atoms of hydrogen per molecule of ammonium dichromate.
Convert grams to mole of molecules. And then molecules to atoms.
55.90 / 252.07 = moles of molecules
Since there are 8 hydrogen per 1 molecule multiply this by 8.
55.90 * 8 / 252.07 = 1.77 moles of hydrogen
