    0.34 moles of oxygen consumed 0.68 moles of magnesium

    Explanation:

    Given dа ta:

    Moles of magnesium = ?

    Moles of oxygen = 0.34 mol

    Chemical equation:

    2Mg + O₂ → 2MgO

    Now we will compare the moles of oxygen and magnesium:

    O₂ : Mg

    1 : 2

    0.34 : 2*0.34 = 0.68 mol

    Thus 0.34 moles of oxygen consumed 0.68 moles of magnesium.
