A 10.0 g sample of magnesium is completely burned in the presence of air to form magnesium oxide. The mass of magnesium oxide must be A. equal to 10.0 g. B. equal to 42.0 g. C. less than 10.0 g. D. greater than 10.0 g. E. equal to 26.0 g
Answer:
D. greater than 10.0 g. Because the oxygen that combines with the magnesium will add to its weight.
