1. Find the molar mass of ammonium bicarbonate:
* N: 14.01 g/mol
* H: 1.01 g/mol (there are 5 hydrogen atoms)
* C: 12.01 g/mol
* O: 16.00 g/mol (there are 3 oxygen atoms)
Molar mass of NH₄HCO₃ = (14.01) + (5 * 1.01) + (12.01) + (3 * 16.00) = 79.06 g/mol
2. Calculate the mass of nitrogen in one mole of ammonium bicarbonate:
* There's one nitrogen atom per molecule of ammonium bicarbonate.
* Mass of nitrogen = 14.01 g/mol
3. Calculate the mass percent of nitrogen:
* Mass percent of N = (mass of N / molar mass of NH₄HCO₃) * 100%
* Mass percent of N = (14.01 g/mol / 79.06 g/mol) * 100%
* Mass percent of N ≈ 17.7%
Therefore, the mass percent of nitrogen in ammonium bicarbonate is approximately 17.7%.
