How many atoms make up 1 molecule of ammonia?

Answer 1

Ammonia = NH3 and has a molar mass of 17.031 g/mol
moles NH3 = 63.9 g x 1 mol/17.031 g = 3.752 moles
molecules NH3 = 3.752 moles x 6.02x10^23 molecules/mole = 2.259x10^24 molecules
Each molecule of NH3 has 4 atoms (1 N + 3 H), thus....
number of atoms = 4 atoms/molecule x 2.259x10^24 molecules = 9.04x10^24 atoms (to 3 sig figs)

Answer 2

For how much?

There are different amounts of atoms in different quantities of ammonia. State the amount of ammonia you are talking about otherwise the question is unanswerable.

2Ca(NO3)2?

Answer 3

First get the formula for ammonia. It is NH3.

Next you need the molecular weight of an ammonia molecule, which based on the formula NH3 is

14 + 3*1 = 17 grams per mole.

Then you need Avogadro's number N = 6.02 x 10^23 molecules per mole.

So 1 gram of ammonia is 1/17 of a mole, containing N/17 molecules.

The number of atoms is 4 times that, because ammonia molecules each contain 4 atoms.

Answer 4

3 hydrogen atoms and 1 nitrogen atom makes one molecule of amonia(NH3).

Answer 5

The molecular formula for ammonia is NH3. It has 1 nitrogen atom and 3 hydrogen atoms for a total of 4 atoms per molecule.

Answer 6

One molecule of ammonia, with the chemical formula NH3, is composed of one nitrogen atom and three hydrogen atoms, totaling four atoms.

Answer 7

Ammonia is NH3 so it has 4 atoms

Answer 8

Ammonia has 3 hydrogen atoms.
