    Answer is: 0,275 moles of oxygen are consumed.

    Chemical reaction: 2Mg + O₂ → 2MgO.

    n (Mg) = 0,550 mol.

    n (O₂) = ?

    from chemical reaction: n (Mg) : n (O₂) = 2 : 1.

    0,550 mol : n (O₂) = 2 : 1.

    2n (O₂) = 0,550 mol.

    n (O₂) = 0,275 mol.

    n - amount of substance.
