How many molecules of Mg3N2 (magnesium nitride) are formed when excess Mg (magnesium)
reacts with 24.3 moles of N2 (nitrogen gas)?
3Mg(s) + N2(g) β Mg3N2(s) 43.1 molecules Mg3N2
32.5grams of NaOH (sodium hydroxide) reacts an excess of CO2 (carbon dioxide).
2NaOH(s) + CO2(g) β Na2CO3(s) + H2O(l)
a. What is the theoretical yield of Na2CO3 in grams? 43.1g Na2CO3
b. If 16.45 g of Na2CO3 is formed, what is the percent yield? 38.2%
