Answer 1

Answer:

6moles of water

Explanation:

Given parameters:

Number of moles of oxygen  = 3moles

  Reaction equation:

      2H₂   +   O₂   →   2H₂O

Unknown:

Number of moles of water formed  = ?

Solution:

To solve this problem;

      compare the number of moles in the reaction.

        1 mole of oxygen gas will produce 2 mole of water

        3 moles of oxygen gas will produce 3 x 2  = 6moles of water.
