From the equation, we can see that the ratio of NH3 to NO is 1:1. Therefore, if 104 g of NH3 is consumed in a 100% yield, the mass of NO produced will also be 104 g. However, we must convert the formula weight of NH3 (17 g/mol) to the formula weight of NO (30 g/mol) to determine the mass of NO produced.

104 g NH3 x (1 mol NH3/17 g NH3) x (1 mol NO/1 mol NH3) x (30 g NO/1 mol NO) = 180 g NO

Therefore, the mass of NO expected is 180 g. Choice C is correct.

Use the Equation NH3 + O2 → NO + H2O

Use the Equation NH₃ + O₂ → NO + H₂O
