Answer: 15 moles of silver chloride will be produced.
Step-by-step explanation:
We are given:
Moles of silver nitrate = 15 moles
For the given chemical reaction:

By Stoichiometry of the reaction:
1 mole of silver nitrate produces 1 mole of silver chloride.
So, 15 moles of silver nitrate will produce =
of silver chloride.
Hence, 15 moles of silver chloride will be produced.
