    0.4 moles of water produced by 6.25 g of oxygen.

    Explanation:

    Given dа ta:

    Mass of oxygen = 6.25 g

    Moles of water produced = ?

    Solution:

    Chemical equation;

    2H₂ + O₂ → 2H₂O

    Number of moles of oxygen:

    Number of moles = mass / molar mass

    Number of moles = 6.35 g / 32 g/mol

    Number of moles = 0.2 mol

    Now we will compare the moles of oxygen with water:

    O₂ : H₂O

    1 : 2

    0.2 : 2*0.2 = 0.4 mol

    0.4 moles of water produced by 6.25 g of oxygen.
