51.3 gram of water should form if 32.5 g of NH₃ react with enough oxygen.
<h3>How to find the Number of moles ?</h3>To calculate the number of moles use the formula
Number of moles =
=
= 1.9 mol
4NH₃ + 5O₂ → 4NO + 6H₂O
4 mol of NH₃ react with oxygen to given 6 mole of water.
So 1.9 mol of NH₃ produces =
= 2.85 mol of water
Mass of water = Molar Mass of water × Number of moles of water
= 18 × 2.85
= 51.3 gram
Thus from the above conclusion we can say that 51.3 gram of water should form if 32.5 g of NH₃ react with enough oxygen.

Answer: The theoretical yield is 6 rings.
Explanation:
Theoretical yield is predicted or estimated value.
Jeweler used 2 sapphires for 1 ring
Then for each sapphire there will be = rings are used
For 12 sapphire = will be used
Out of 10 rings 6 rings with 2 sapphires will be made.
The theoretical yield is 6 rings.
