20 moles of nh3 are needed to produce how many moles of h2o.

Solution:

NH₃ reacts with oxygen to produce H₂O as follows:

$$4 \mathrm{NH_3}(g) + 7 \mathrm{O_2}(g) = 4 \mathrm{NO_2}(g) + 6 \mathrm{H_2O}(g)$$

According to equation 4 moles of NH₃ are needed to produce 6 moles of H₂O, so 20 moles of NH₃ produce

$$\frac{20 \cdot 6}{4} = 30$$

moles of H₂O.

**Answer:** 30 moles of H₂O.
