Question

Gaseous ammonia chemically reacts with oxygen (O₂) gas to produce nitrogen monoxide gas and water vapor. Calculate the moles of water produced by the

reaction of 0.095 mol of oxygen. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits

Answer 1

The balanced chemical equation for the reaction between gaseous ammonia and oxygen gas is:

4NH3 + 5O2 -> 4NO + 6H2O

From this equation, we can see that for every 4 moles of ammonia, 6 moles of water are produced. Thus, with 0.095 moles of oxygen, we can calculate the number of moles of water produced using the stoichiometric ratio of the reactants:

0.095 moles of O2 x (6 moles H2O/5 moles O2) = 0.114 moles H2O

Therefore, 0.114 moles of water are produced by the reaction of 0.095 moles of oxygen.
