Add the number of Protons and the number of Neutrons.
The answer is 14 Atomic Mass
Ammonium hydrogen sulfate, (NH4)HSO4, contains one nitrogen atom in the ammonium ion. To calculate the percentage of nitrogen by mass, you would find the molar mass of nitrogen in the compound and divide it by the molar mass of the entire compound, then multiply by 100 to get the percentage.
That should be mass, not weight. The mass of one atom of Ag doesn't depend on the size of the sample. Also, you can't "calculate" the mass of one atom from the information provided. You can look it up - or you can look up the atomic mass of Ag, and multiply it by the atomic mass unit.
Nitrogen monoxide is one nitrogen molecule (atomic weight 14) combined with one oxygen molecule (atomic weight 16). The atomic weight for NO is (14 +16 =) 30. Nitrogen dioxide is one nitrogen molecule (atomic weight 14) combined with two oxygen molecules (atomic weight 16). The atomic weight for NO2 is [14 + (2×16)] = 46. Nitrogen also forms a few more stable oxides; N2O Nitrous Oxide (Laughing Gas), NO3 Nitrogen Trioxide, and N2O5 Di-nitrogen Pentoxide (Nitric Acid Anhydride). H_AMMER
To find the mass percent of nitrogen in NF3, you need to calculate the molar mass of NF3 and then determine the mass of nitrogen in one mole of NF3. The molar mass of NF3 is 71.001 g/mol. The molar mass of nitrogen in NF3 is 14.007 g/mol. Therefore, the mass percent of nitrogen in NF3 is (14.007 g/mol / 71.001 g/mol) * 100% ≈ 19.76%.
The gram atom mass of 5 nitrogen atoms is 5 times the gram atom mass for a single nitrogen atoms, which can be found, in a periodic table or other reference, to be 14.007. Therefore the gram atom mass of 5 N atoms is 5 X 14.007 = 70.035. 23.4 % = 0.234. From the problem statement, the unknown molar mass M of the substance obeys the relationship 0.234 M = 70.035, or M = 299, to the justified number of significant digits.

The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.
Nitrogen Atomic mass is 14.0067 ± 0.0002 u
14 A proton has an atomic mass of approximately 1 AMU. A neutron also has an atomic mass of approximately 1 AMU. For most purposes, the atomic mass of an electron is considered to be negligible. Without knowing the number of protons this atom contains, one cannot calculate the atomic mass of the atom.

The molecular formula NO represents a single nitrogen atom bonded to an oxygen atom, while the molecular formula N2O represents two nitrogen atoms bonded to one oxygen atom. Thus, the composition and arrangement of atoms in the two molecules differ.

The formula for nitrogen monoxide is NO. It consists of one nitrogen atom and one oxygen atom.
To calculate total nitrogen, you typically sum up the concentrations of different forms of nitrogen present in a sample. This can include organic nitrogen, ammonia nitrogen, nitrite nitrogen, and nitrate nitrogen. Analytical techniques such as Kjeldahl digestion or combustion methods are commonly used to determine total nitrogen content in a sample.
