Question

calculate the gram molar mass of NH3​

Answer 1

Answer:

GMW = 14+3(1) = 17 gm

Therefore gmw of NH3 is 17gm

Answer 2

Answer:

Explanation:

To determine the molar mass of any compound, all you have to do is add up the molar masses of every atom that makes up the respective compound.

In this case, you know that ammonia,

NH

3

, is composed of

one nitrogen atom,

N

three hydrogen atoms,

H

This means that its molar mass will be the sum of the molar mass of one nitrogen atom and three times the molar mass of a hydrogen atom.

A quick look in the periodic table will show that you have

N:

14.0067 g/mol

H:

1.00794 g/mol

The molar mass of ammonia will thus be

14.0067 g/mol

+

3

×

1.00794 g/mol

=

17.03052 g/mol
