Consider the following equation:

\[ 4\text{NH}_4 + 5\text{O}_2 \rightarrow 4\text{NO} + 6\text{H}_2\text{O} \]

How many moles of water are produced when 2 moles of \(\text{NH}_4\) react with excess oxygen gas?

see we have two moles of NH4, so we replace 4 NH4 by 2 NH4. Now, on balancing the equation, we get 2 NH4 + 3O2 ---> 2NO + 4 H2O (law of conservation of mass) thus, 2 moles of NH4 react with 3 moles of oxygen gas to produce 2 moles of NO2 and 4 moles of H2O. Thus, we get 4 moles of H2O

The **moles **of water are produced when 2 moles of NH4 react with excess Oxygen gas is 4 mole of H2O.
What is moles?

**Moles **are defined as a **common unit **used in **science **to measure vast numbers of extremely small things, such atoms, molecules, or other specific particles.
It can also be defined as a **metric **in chemistry that is used to **describe **a very **high quantity **of molecules , atoms, or particles.
Since we only have two moles of NH4, we switch out four for two.
2 NH4 + 3O2 --> 2NO + 4 H2O
As per the reaction, in order to produce 2 moles of NO2 and 4 moles of H2O, 2 moles of NH4 must react with 3 moles of oxygen gas.
Thus, the **moles **of water are produced when 2 moles of NH4 react with excess Oxygen gas is 4 mole of H2O.

When 2 moles of NH 4 ​ react with excess oxygen gas, 3 moles of water are produced. This is determined by the mole ratio in the balanced chemical equation. Using a proportion based on the coefficients reveals this relationship clearly.
