Answer: The amount of water formed in the reaction are 4.0 moles
Step-by-step explanation:
We are given:
Moles of hydrogen gas = 4.0 moles
For the given chemical reaction:
By Stoichiometry of the reaction:
2 moles of hydrogen gas produces 2 moles of water.
So, 4.0 moles of hydrogen gas will produce =
of water.
Hence, the amount of water formed in the reaction are 4.0 moles
