Chapter 4, Problem 4.107PAE

4.107 Existing stockpiles of the refrigerant Freon-12, CF₂Cl₂ must be destroyed under the terms of the Montreal Protocol because of their potential for banning the ozone layer. One method for doing this involves reaction with sodium oxalate:

${\text{CF}}_{\text{2}}{\text{Cl}}_{\text{2}}+{\text{ 2 Na}}_{\text{2}}{\text{C}}_{\text{2}}{\text{O}}_{\text{4}}\to \text{ 2 NaF }+\text{ 2NaCl }+\text{ C }+{\text{ 4CO}}_{\text{2}}\mathbb{S}$

If you had 150 tons of Freon-12, describe how you would know how much sodium oxalate you would need to make that conversion.
