How many hydrogen atoms are in 5.70 mol of ammonium sulfide?

There are 2.74603 * 10^25 hydrogen atoms. Ammonium sulfide is represented by (NH4)2S. This means that there are 8 hydrogen atoms total. There are also 8 mol of H in ammonium sulfide. We also need to use avogadro’s number of 6.022 * 10^23. Hydrogen Atoms = 5.7mol * (8mol / 1mol) * 6.022 * 10^23 per mol Hydrogen atoms = 2.74603 * 10^25 hydrogen atoms.

The phase where ice changes directly to gas is called sublimation
