Your compound's chemical formula is (NH4)2Cr2O7 - so you can see that it contains 2 moles of NH4+ per mole of the salt. So in 7 moles you have 14 moles of ammonium, containing 14 moles of N atoms which means that you have (1 mole = 6,022*10^23 atoms) 14 mols * 6,022*10^23 atoms/mole = 8,43*10^23 atoms
This formula is itself an ion with -2 charge. It has 2 carbon atoms and 4 oxygen atoms per ion. An oxalate ion has six atoms.
there are 1.30e25 Hydrogen atoms in 2.70 mol Ammonium Sulfide
4,2.10e25 H atoms
The formula for ammonium sulfide is (NH4)2S. Therefore, each formula unit contains 8 hydrogen atoms.
The formula unit for ammonium sulfide has the formula (NH4)2S. This formula shows that the formula unit contains two ammonium ions, each of which contains four hydrogen atoms. The total number of hydrogen atoms is therefore 8.

The formula for ammonium sulfate is; (NH4)2SO4 ( NH4 is 1+ and SO4 is 2- ) So, there are 8 hydrogen atoms in ammonium sulfate.
Chemical formula for Ammonium Carbonate: (NH4)2CO3 So there are two Nitrogen atoms in that molecule.
Your compound's chemical formula is (NH4)2Cr2O7 - so you can see that it contains 2 moles of NH4+ per mole of the salt. So in 7 moles you have 14 moles of ammonium, containing 14 moles of N atoms which means that you have (1 mole = 6,022*10^23 atoms) 14 mols * 6,022*10^23 atoms/mole = 8,43*10^23 atoms
non formula: NH4Cl
Aluminum dichromate has the formula unit of Al2(Cr2O7)3. This means there are two aluminum, six chromate and 21 oxygen atoms present for a total of 29 atoms.
Diammonium phosphate - (NH4)2HPO4 - has 9 hydrogen atoms in the formula unit.
Ammonium sulphate (NH4)2SO4 contains two ammonium ions per unit so there are total 8 hydrogen atoms.
The answer will depend on how much ammonium carbonate. In one molecule of the substance, there are 8.
