Answer:
The mass of ammonia (NH3) that contains
hydrogen atoms is
g.
Explanation:
As
atoms of hydrogen = 1 mole of the hydrogen atom
Therefore,
atoms of hydrogen
moles of the hydrogen atom.
Now, there are 3 moles of hydrogen atoms in 1 mole of ammonia
.
As the mass of 1 mole of ammonia is 17g, so
when there are 3 moles of hydrogen atoms, then the mass of ammonia = 17 g
Therefore, when there are
moles of hydrogen atoms, then the mass of ammonia
g.
Hence, the mass of ammonia
that contains
hydrogen atoms is
g.
