How do you calculate the molar mass of ammonia?
To calculate molar mass, you use the following formula.Molar Mass = Given mass / number of moles.For example if you are given that there is 85 gram of ammonia and it is 5 moles. Then Molar Mass = 85/5 = 17 g.
If the atomic mass of ammonia?
Ammonia doesn't have an atomic mass as such (from a practical chemistry point of view), because it is a molecular compound comprised of one nitrogen atom and three hydrogen atoms.The atomic mass of an element is the number of protons and neutrons (you should really include the electrons as well which is why the atomic masses on you periodic table have some decimal points) in the nucleus of an atom, so H has an atomic mass of 1 (because the nucleus is a single proton) and N has the atomic mass of 15.(As an aside don't confuse atomic mass with atomic number, which is just the number of protons in the nucleus (7 for nitrogen). Look at a periodic table and you'll soon see which is which.)So, you could say that the "atomic mass" of ammonia (NH3) is the sum of its constituent atoms i.e. 18, but that isn't really very useful in my experience.What might be more practically useful is to understand how this relates to the "molar mass" of ammonia, which is the mass of 1 mol of ammonia. 1 mole of any compound (or element) contains EXACTLY 6.02 x 10^23 molecules. That can be calculated by adding up the atomic masses of your compound. E.G. 1 mole of N will have a mass of 15 metric grams. 1 mole of hydrogen will have a mass of 1 gram (see where this is going?!)Interestingly, whilst 1 mole of hydrogen would mass only a single gram, 1 mole of lead would mass over 200g even though they contain the EXACT SAME NUMBER OF ATOMS!!
What is the mass percentage of hydrogen in ammonia?
The molar mass of ammonia (NH3) is 17.03 g/mol. Hydrogen's molar mass is 1.01 g/mol. The mass of hydrogen in ammonia is 3.03 g (3*1.01). To find the mass percentage of hydrogen in ammonia: (3.03 g / 17.03 g) * 100% ≈ 17.8%.
Atomic number for ammonia?
Ammonia does not have an atomic number, as it is a molecular compound composed of nitrogen and hydrogen atoms. The atomic number refers to the number of protons in an atom's nucleus, and since ammonia is a compound, it does not have a single atomic number.
What is mass of ammonia?
The molecular mass of ammonia (NH3) is 18.03 grams/mole

What is ammonia's atomic number?
Ammonia = NH3 Ammonium = NH4
What is the mass percentage of hydrogen in ammonia?
The molar mass of ammonia (NH3) is 17.03 g/mol. Hydrogen's molar mass is 1.01 g/mol. The mass of hydrogen in ammonia is 3.03 g (3*1.01). To find the mass percentage of hydrogen in ammonia: (3.03 g / 17.03 g) * 100% ≈ 17.8%.

What is the mass percentage of nitrogen in ammonia?
The mass percentage of nitrogen in ammonia (NH3) is 82.35%. This is calculated by dividing the mass of nitrogen in one mole of ammonia by the molar mass of ammonia, and then multiplying by 100 to get the percentage.
0.085g of amonia is to how many moles?
The calculation is: Moles = Mass / Atomic Mass Moles = 0.085 / 17 Moles = 0.005 Atomic mass is 17 because ammonia is NH3, with N = 14, and H = 1. 14 + 1 + 1 + 1 = 17.
100 grams of ammonia equals how many moles?
For this you need the atomic (molecular) mass of NH3. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. NH3=16.0 grams100 grams NH3 / (16.0 grams) = 6.25 moles NH3
What is mass of ammonia?
The molecular mass of ammonia (NH3) is 18.03 grams/mole
What is the atomic number or ammonia?
The atomic number of ammonia (NH3) is zero, as it is a compound made up of nitrogen and hydrogen atoms. Each individual nitrogen atom has an atomic number of 7, and each hydrogen atom has an atomic number of 1.
What is the percentage by mass of hydrogen in ammonia?
Mass of ammonia is 17. Mass of Hydrogen in it is 3. So the percentage of hydrogen by mass is 17.64%
What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
