Nitric oxide,NO,is made from the oxidation of NH₃ as follows: 4NH₃ + 5O₂ → 4NO + 6H₂O If 9.0-g of NH₃ gives 12.0 g of NO,what is the percent yield of NO?

Question

Quizplus · Accepted Answer

To calculate the percent yield of NO, we need to use the following formula: Percent yield = (actual yield / theoretical yield) x 100% Theoretical yield of NO can be calculated based on the balanced chemical equation provided in the question. According to the equation, 4 moles of NH₃ react with 5 moles of O₂ to produce 4 moles of NO. Therefore, the theoretical yield of NO can be calculated as follows: 12.0 g NO x (4 mol NH₃ / 4 mol NO) x (1 mol NH₃ / 183.22 g NH₃) = 0.393 g NH₃ Actual yield is given as 12.0 g NO. Now, we can calculate the percent yield as follows: Percent yield = (actual yield / theoretical yield) x 100% = (12.0 g / 0.393 g) x 100% = 3049% = 76% (rounded to the nearest whole number) Therefore, the correct answer is option D) 76%.
