    Magnesium can be used as a "getter" in evacuated enclosures, to react with the last traces of oxygen. (The magnesium is usually heated by passing an electric current through a wire or ribbon of the metal.)

    If an enclosure of 0.384 L has a partial pressure of O2 of 3.6×10−6 torr at 28 C degrees, what mass of magnesium will react according to the following equation? 2Mg(s)+O2(g)>>2MgO(s)

    Express your answer using two significant figures.
