Balanced equation first.
3Mg + N2 -> Mg3N2
55.3 grams Mg (1 mole Mg/24.31 grams)(1 mole Mg3N2/3 mole Mg)(100.95 grams/1 mole Mg3N2)
= 76.5 grams Mg3N2 made

What is the molar mass of magnesium nitride (Mg3N2) if the molar mass of magnesium is 24.31g and nitrogen is 14.01g?
Need formula of magnesium nitride, an ionic compound. Mg2+ and N3- together make Mg3N2 -------------- so 3 * 24.31 g = 72.93 grams 2 * 14.01 g = 28.02 grams ------------------------------------------add = 100 .95 grams/mole --------------------------------molar mass magnesium nitride

When magnesium burns in pure nitrogen gas magnesium nitride is formes what mass of magnesium must be provided in order to produce 1.19 grams of magnesium nitride?
3Mg + N2 --> Mg3N2 molar mass of Mg3N2: 100.9494 g/molmolar mass of Mg: 24.305 1.19g Mg3N2 * 1mol/100.9494g * 3mol Mg/1mol Mg3N2 * 24.305g/1mol = 0.860g
How many nitrogen atoms are in 18.8 g of barium nitride?
Barium nitride is Ba3N2 (from the rules of ionic bonding). Its molar mass is 439 grams/mole (from the periodic table), so 18.8 grams of it is 0.0428 moles (by algebraic direct proportion). Multiply this by Avogadro's number (6.02x1023; the number of particles in 1 mole) and you get 2.58x1022 formula units of barium nitride, and there are 2 nitrogen atoms per formula unit, so double it to 5.16x1022 atoms of nitrogen.

How many moles of nitrogen gas are produced when ammonium nitrate reacts?
1 mole of ammonium nitrate produces one mole of nitrogen. Actually the amount (in moles) of nitrogen will depend on how much NH4NO3 you are starting with, what other reactant you are combining it with and whether or not the NH4NO3 completely reacts. Since you will never be able to retrieve all of the nitrogen (either the NH4 or the NO3 will retain some nitrogen depending upon the reaction), you can reasonably expect to get 1 mole of N2 for each 14.01 grams of Ammonium nitrate that COMPLETELY reacts.
