Nitrogen has an average Atomic Mass of about 14 while hydrogen has an average atomic mass of about 1, so the total molecular mass of NH3 is about 17. From this we find that the mass percentage of N in NH3 is about 14/17 = 82%. To get more precise numbers, look up the exact atomic masses from a Periodic Table.

The molar mass of NH3 is 17 g/mol (1 N atom + 3 H atoms). The molar mass of N in NH3 is 14 g/mol. To calculate the mass percentage of N in NH3, divide the molar mass of N by the molar mass of NH3 and multiply by 100. 14 g/mol / 17 g/mol * 100 ≈ 82.4%. So, the mass percentage of N in NH3 is approximately 82.4%.

What is the mass of 1 mole of NH3?
the molecular mass number of NH3 = 17 atomic mass no.of N=14 x 1 atom (present in the compound)=14 atomic mass of H= 1 x 3 atoms (present in compound)=3 thus, molecular mass= atomic mass of N+ atomic mass of H3 = 14 + 3 = 17
How many grams of NH3 can be produced from 4.10 moles of N and excess H?
Four moles of NH3 can be produced from 4.10 moles of N, as the stoichiometry of the reaction is 1:1 for N to NH3. The molar mass of NH3 is roughly 17 g/mol, so 4.10 moles of N will produce approximately 69.7 grams of NH3.
What is can the mass NH3 made if they give you the gram?
To find the mass of NH3 produced, first calculate the number of moles of NH3 using the given mass and the molar mass of NH3. Then, use the relationship between moles and mass (mass = moles x molar mass) to find the mass of NH3.
What is the mass of 1.75 1024 molecules of NH3?
To find the mass of 1.75 x 10^24 molecules of NH3, you would first calculate the molar mass of NH3 (17.03 g/mol). Then, you would convert the number of molecules to moles by dividing by Avogadro's number (6.022 x 10^23 molecules/mol). Finally, multiply the number of moles by the molar mass to find the mass.
What is the molecular mass of ammonia NH3?
The molecular mass of ammonia (NH3) is approximately 17.03 grams per mole.
What is the molecular mass of NH3 when The atomic mass of N is 1401 gmole and the atomic mass of H is 1008 gmole?
Molecular mass = sum of all atoms masses = 1(molN/mol NH3)*14.01(g/mol N) + 3(molH/mol NH3)*1.008(g/mol H) = 17.03 g/mol NH3
What is the percentage composition of ammonia NH3?

What is the molecular mass of ammonia NH3?
The molecular mass of ammonia (NH3) is approximately 17.03 grams per mole.
What is the richest source of nitrogen on a mass percentage?
The richest source of nitrogen on a mass percentage is the atmosphere, where it makes up about 78% of the air we breathe. Nitrogen gas (N2) is abundant in the atmosphere but not readily available for use by most organisms in that form.
Calculate mass in grams of 2.110 moles of NH3?
You can find the mass of one mole of each of the individual elements by looking at the mass numbers.So, 1 mole of:N=14gH=1gsince there are 3 H's the total mass of 1 mole NH3 is 14+3=17gYou then multiply the actual number of moles by the g's per mole:=> 17x2.11=35.87g
How many moles of NH3 is in 23g of NH3?
Atomic mass of NH3 is 17.So there are 1.353mol.
What is the oxidation state of N in NH3?
N has +3 state on it.Each H have -1 state.
