How many hydrogen atoms are in 7.80 mol of ammonium sulfide?

There are number of H atoms in 7.80 mol of ammonium sulfide.

Explanation:

The formula of ammonium sulfide is .

There are 2 nitrogen atoms, 8 hydrogen atoms and 1 sulfur atom in one molecule of ammonium sulfide.

Calculate moles of hydrogen atoms as follows.

              = 62.4

According to Avogadro's number 1 mole contains

Therefore, calculate number of H atoms as follows.

             =

             =

Thus, there are number of H atoms in 7.80 mol of ammonium sulfide.

fe 55.85 g/mol and h2o 18.02 g/mol.
