Question

1)What is the mass of Nitrogen in NH3? (use two decimal places)

2)What is the TOTAL mass of Hydrogen in NH3? (use two decimal places)

3)What is the Molar Mass of NH3? (use 2 decimal places)

Answer 1

1) The Mass of Nitrogen in
`NH_3` is 14.00 gm.

2) The Mass of Hydrogen in
`NH_3` is 3.00 gm.

3)The Molar Mass of
`NH_3` is 17.00 gm.

Explanation:

Solving for Part 1.

In
`NH_3` that is Ammonia there is 1 atom of Nitrogen.

So the atomic mass of Nitrogen is same as the mass of Nitrogen in
`NH_3`.

Atomic mass of Nitrogen = 14.00 gm

Hence The Mass of Nitrogen in
`NH_3` is 14.00 gm.

Solving for Part 2.

In
`NH_3` there are 3 atoms of Hydrogen.

Atomic mass of Hydrogen = 1.00 gm

So the mass of Hydrogen in
`NH_3` is 3 times of its atomic mass.

Mass of Hydrogen = 3 × Atomic mass of Hydrogen

`Mass\ of\ Hydrogen =3*1.00=3.00\ gm`

Hence The Mass of Hydrogen in
`NH_3` is 3.00 gm.

Solving for Part 3.

In
`NH_3` 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
`NH_3`.

Molar mass of
`NH_3`=Mass of Nitrogen+Mass of Hydrogen

`Molar\ mass\ of\ NH_3=14.00+3.00=17.00\ gm`

Hence The Molar Mass of
`NH_3` is 17.00 gm.
