1a) How many moles of chlorine gas (Cl2) would react with 5 moles
of sodium (Na) according to the following chemical equation?
(Balance equation.)
2 Na + Cl2 --> 2 NaCl
5 mol Na|1 mol Cl2 = 2.5 mol Cl2
|2 mol Na
1b) Using the equation (after it is balanced) above, determine the
mass of product that can be produced from 24.7 g Na.
24.7g Na |1 mol Na |2 mol NaCl |58g NaCl = 62 g NaCl
| 23 g Na |2 mol Na |1 mol NaCl
1c) How many liters of chlorine are needed to react with 24.7g Na?
24.7g Na |1 mol Na |1 mol Cl2 |22.4 L Cl2 = 12 L Cl2
|23 g Na |2 mol Na |1 mol Cl2

2 C8H18 + 25 O2 --> 16 CO2 + 18 H2O
2) If 27.3g of C8H18 are combusted, what mass of water will be
produced?
27.3 g C8H18 |1 mol C8H18 |18 mol H2O |18g H2O = 38.8 g H2O
|114g C8H18 |2 mol C8H18 |1 mol H2O
