Question

4 NH3(g) + 5O2(g) → 4NO(g) + 6H2O(g)

How many moles of water will result from the reaction of 0.75 mol of oxygen?

Answer 1

0.9 moles of water

Step-by-step explanation:

Use mole ratios:

5 : 6

divide by 5 on both sides

1 : 1.2

multiply by 0.75 on both sides

0.75 : 0.9

So the result is 0.9 moles of water
