The mass % of N in (b) ammonium nitrate is 17.50%.
The ratio of a solute's mass in a solution to the total mass of the solution is known as the mass percent of a solution. A concentration is described as having a "mass percent." The component of a mixture is also identified by it. You can comprehend the solution composition by using a mass percentage. The amount of solute in a specific volume of solution is indicated.
The mass of the solution is calculated as:
the mass of the atom × number of atoms,
mass of solution = 2 × 14 g/mol + 4 × 1 g/mol + 3 × 16 g/mol
mass of solution = 80 g/mol
mass of nitrogen = 14 g/mol
The mass percent of nitrogen can be calculated:
mass % N = mass of N / mass of solution * 100
mass % N = 14 g/mol / 80 g/mol * 100
mass % N = 17.50 % .
