Answer:
1) The Mass of Nitrogen in
is<u> 14.00 gm.</u>
2) The Mass of Hydrogen in
is<u> 3.00 gm.</u>
3<u>)</u>The Molar Mass of
is <u>17.00 gm.</u>
Step-by-step explanation:
Solving for Part 1.
In
that is Ammonia there is 1 atom of Nitrogen.
So the atomic mass of Nitrogen is same as the mass of Nitrogen in
.
Atomic mass of Nitrogen = 14.00 gm
Hence The Mass of Nitrogen in
is<u> 14.00 gm.</u>
<u />
Solving for Part 2.
In
there are 3 atoms of Hydrogen.
Atomic mass of Hydrogen = 1.00 gm
So the mass of Hydrogen in
is 3 times of its atomic mass.
Mass of Hydrogen = 3 × Atomic mass of Hydrogen

Hence The Mass of Hydrogen in
is<u> 3.00 gm.</u>
<u />
Solving for Part 3.
In
there is 1 atom Nitrogen and 3 atoms of Hydrogen.
So molar mass is the sum of mass of nitrogen and mass of Hydrogen in
.
Molar mass of
=Mass of Nitrogen+Mass of Hydrogen

Hence The Molar Mass of
is <u>17.00 gm.</u>
