Magnesium and nitrogen react to produce magnesium nitride, according to the reaction below.  If 10.52 grams of N2 react completely.  How much Mg is consumed?



Step-by-Step

1.  Use the molar mass of N2 to convert grams of N2 to moles.
2.  Convert the moles of N2 to moles of Mg by using the mole ratio from the chemical equation (3 mol Mg = 1 mol N2).
3.  Finally, use the molar mass of magnesium to calculate grams of Mg.
