To help farmers and gardeners, commercial fertilizers have a big three-number "NPK" label on the bag that gives the amounts of three key plant nutrients: nitrogen, phosphorus, and potassium. For example, a bag of "10–10–10" fertilizer has 10% by mass nitrogen, 10% by mass potassium as potash (K₂O), and 10% by mass phosphorus as phosphate (P₂O₅).Suppose a certain fertilizer has the following composition:| Ingredient | Percent by Mass ||---------------------------------|-----------------|| Ammonium phosphate ((NH₄)₃PO₄) | 14% || Urea ((NH₂)₂CO) | 36% || Potassium sulfate (K₂SO₄) | 44% || Inert ingredients | 6% |What should the first (nitrogen) number on the bag label be? That is, calculate the percent by mass of nitrogen in this fertilizer. Round your answer to the nearest percent.**Explanation:**To find the nitrogen content, we calculate the contribution of nitrogen from each nitrogen-containing compound.1. **Ammonium phosphate ((NH₄)₃PO₄)**: - Contains three ammonium ions, each with one nitrogen atom. - Molar mass of ammonium phosphate ≈ 149 g/mol - Molar mass of nitrogen in (NH₄)₃PO₄ = 3 x 14 g/mol = 42 g/mol - Percent nitrogen in (NH₄)₃PO₄ = (42/149) x 100 ≈ 28.19% - Contribution to fertilizer: 14% (mass) x 28.19% ≈ 3.9466%2. **Urea ((NH₂)₂CO)**: - Contains two nitrogen atoms. - Molar mass of urea ≈ 60 g/mol - Molar mass of nitrogen in urea = 2 x 14 g/mol = 28 g/mol - Percent nitrogen in urea = (28/60) x 100 ≈ 46.67% - Contribution to fertilizer: 36% (mass) x 46.67% ≈ 16.8%Add both contributions: 3.9466% +
