1. Suppose that in the experiment of the empirical formula 10% of the metal (Mg) stays unreacted and does
not get converted to oxide, how this error will affect the reported mass of:
(a) Magnesium in the sample? Explain.
(b) Oxygen in the sample? Explain.
2. When the magnesium is not allowed sufficient air (oxygen) in step (4) some magnesium nitride
(Mg3N2 ) forms. If the MgsN2 is not decomposed in step (6), will the reported Mg to O mole ratio be
high or low? Explain.
