in the experiment water was added to convert the small amount of magnesium nitride (Mg3N2) produced into magnesium oxide (MgO). suppose this step was skipped so that the solid magnesium nitride impurity was allowed to remain in the product, and the product was analyzed as if it were pure magnesium oxide (MgO). In the erroneous approach, would the determined mass percent of magnesium in magnesium oxide be higher or lower than the true value? you need to provide a reason for your answer to receive credit.
