A0.941 gram piece of magnesium metal is heated and reacts with oxygen. the resulting oxide weighed 1.560 grams. determine the percent composition of each element in the compound

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.
