The balanced equation of the reaction that they describe to us says:
![CO_2+4NaCl\rightarrow CCl_4+2Na_2O](https://img.qammunity.org/2023/formulas/chemistry/college/88jr5woa3gqmmpfvwu2a0h18nh0b198150.png)
We see that 4 moles of NaCl produce 1 mole of CCl4. Therefore, the CCl4 to NaCl ratio is 1/4. So if we have 1.2 moles of NaCl, the moles of CCl4 that can be produced will be:
![molCCl_4=givenmolNaCl*(1molCCl_4)/(4molNaCl)](https://img.qammunity.org/2023/formulas/chemistry/college/a4czoj16tw39idoyssyh49a9dhk4j4rnhr.png)
![molCCl_4=1.2molNaCl*(1molCCl_4)/(4molNaCl)](https://img.qammunity.org/2023/formulas/chemistry/college/2ktmyhs42xa5vrgipsvfu06xp0wjw05p9l.png)
![molCCl_4=0.3molCCl_4](https://img.qammunity.org/2023/formulas/chemistry/college/843a7hds0owbvh1u9vwapsg1a95wcjglz1.png)
Answer: If we start with 1.2 moles of NaCl, it would be produced 0.3 moles of CCl4
