How many nitrogen in NH3?

Answer 1

You are probably asking about the molar mass of NH3. This is a measure of the amount of grams in one mole of NH3. This can be found by adding the molar masses of each element. Also, you must be sure to multiply each molar mass of an element by the number of atoms of that element that are present. In NH3 there is one nitrogen atom and 3 hydrogen atoms. Nitrogen has a molar mass of 14.01 and Hydrogen has a molar mass of 1.008. Therefore: 1*(14.01) + 3*(1.008) = 17.034 So for every mole of NH3 you will have 17.034 grams.

Answer 2

To find the molecular mass of a compound, add up all the masses of the individual atoms. In ammonia (NH3), we have one nitrogen (14.0 Atomic Mass units), and three hydrogens (1.01 amu each, or 3.03 amu total), so we get a total of 17.0 amu. The conversion for amu's to grams is: 1 amu = 1.66 x 10-24grams, so we find the mass for our ammonia molecule by multiplying 17.0amu x (1.66 x 10-24g/amu) = 2.82 x 10-23g.

Answer 3

One mole of NH3 is approximately 17 grams.

How?

• N, Nitrogen, weighs approximately 14 amu.
• H, Hydrogen, weighs approximately 1 amu.

There is 1 nitrogen and 3 hydrogens in NH3. In total, NH3 weighs approximately 17 amu.

To figure out the gram formula mass, simply multiply the weight in amu by the amount of moles.

1 mol x 17amu = 17 grams

2 mol x 17amu = 34 grams

And so on...

Answer 4

There is one nitrogen atom per molecule of NH3.

Answer 5

1 N = 14 g/mol

3 H's = 3 g/mol

1 NH3 = 17 g/mol

17g x 1 mol

mol 6.022x10^23 NH3's = 2.82x10^-23 g / NH3 molecule

Answer 6

I assume you mean the molecular mass. Its molecular mass is 17g/mol

Answer 7

There is one molecule.There are four atoms

Answer 8

NH3 contains one nitrogen atom.

Answer 9

5.29g
