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.

The formula for sodium nitrate is NaNO3, showing that each formula unit contains one sodium atom, one nitrogen atom, and three oxygen atoms. The gram atomic masses of sodium, nitrogen, and oxygen are 22.9898, 14.0067, and 15.9994 respectively. Therefore, the percentage by mass of nitrogen in the compound is: 100{14.0067/[14.0067 + 22.9898 + 3(15.9994)]} or about 16.4795, to the justified number of significant digits.
You would first calculate the atomic mass of chlorophyll, which would be 892.9 g/mol (I did not calculate this out, but looked it up b/c of the complexity of the calculation). Then find the molar mass of the Nitrogen part of the chlorophyll (4 mol *14.01 g/mol=56.04 grams). Then, take 56.04 grams/892.9grams= .06276, or 6.276% nitrogen by mass
Nitrogen is a non metal element. Atomic mass number of it is 14.
The maximum percentage of nitrogen by mass is about 78.08%, which is the composition of nitrogen gas (N2) in the atmosphere.
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.
The percentage of nitrogen in N2O4 is 63.6%. This is determined by dividing the molar mass of nitrogen in N2O4 by the molar mass of the compound and then multiplying by 100.

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.
The molar mass of aluminum nitrate (Al(NO3)3) is 213 g/mol. The molar mass of nitrogen in the compound is 14 g/mol. Therefore, the percentage by mass of nitrogen in aluminum nitrate is (3 * 14) / 213 * 100 ≈ 19.7%.
Guanidine is a stronger base than ethanamidine because it has three nitrogen atoms in its structure, providing more opportunities to accept protons and increase electron density. This electron density makes guanidine more basic compared to ethanamidine, which has only one nitrogen atom for proton donation.
Guanidine is a strong base because it readily accepts protons (H+) to form guanidinium ions. The lone pair on the nitrogen atom of guanidine can easily abstract a proton from a solution, making it a strong base with high basicity.
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.
The molar mass of calcium nitrate is 164.1 g/mol. The molar mass of nitrogen is 14.01 g/mol. So, the percentage of nitrogen in calcium nitrate is (14.01 g/mol / 164.1 g/mol) * 100% ≈ 8.54%.
Ammonium sulfate has the chemical formula (NH4)2SO4. The molar mass of nitrogen is 14.01 g/mol and the molar mass of (NH4)2SO4 is 132.14 g/mol. Therefore, the percentage by mass of nitrogen in ammonium sulfate is (2*14.01)/(132.14) * 100% = 21.2%.
