5 Stoichiometry Chemistry questions !



1. Determine the mass in grams of lithium hydroxide produced when 0.38 g of lithium nitride reacts. g LiOH

Li3N(s) + 3 H2O(l) --> NH3(g) + 3 LiOH(aq)


2. How many moles of sodium chloride are produced when 2.9 grams of sodium iodide reacts? mol NaCl

2 NaI(s) + Cl2(g) --> 2 NaCl(s) + I2(g)


3. What volume in liters of chlorine gas at STP would be required to fully react with 125 g of NaI? L Cl2

2 NaI(s) + Cl2(g) --> 2 NaCl(s) + I2(g)


4. Determine the volume in liters of carbon dioxide produced at STP when 0.85 grams of butane (C4H10) reacts. L CO2

2 C4H10(l) + 13 O2(g) --> 8 CO2(g) + 10 H2O(g)


5. Calculate the mass in grams of water vapor produced by the combustion of 51.3 L of propane, C3H8, at STP. g H2O

C3H8(g) + 5 O2(g) --> 3 CO2(g) + 4 H2O(g)
