    Given:

    magnesium = 0.941 gram piece

    Magnesium oxide = 1.560 grams

    Formula:

    (magnesium / magnesium oxide) x 100 = % Mg

    100% - % Mg = percent composition of each element

    Solution:

    (0.941g Mg) / (1.560g MgO)

    = 0.603

    = 60.3% Mg

    100% - 60.3%

    = 39.7%

    39.7% is the percentage composition of each element.
