How many moles of NO can be produced from 2.35 g of NH3 according to this reaction: 4 NH3 + 5 02 --> 4 NO + 6H2O

Answer 1

First use the g of NH₃ and its MW to convert g to moles.

2.35 g NH₃ x (1 mol NH₃ / 17.03 g NH₃) = 0.138 mol NH₃

Next, from the balanced chemical reaction, 4 moles of NH₃ reacts to form 4 moles of NO. The mole ratio is 4:4. Use this mole ratio for the stoichiometry conversion.

0.138 mol NH₃ x (4 mol NO / 4 mol NH₃) = 0.138 mol NO
