Answer: 0.113 moles of NaCl are created as a result of decomposing 12 grams of  .
.
Explanation:
To calculate the moles :
 
   

The balanced chemical equation for decomposition of  is:
 is:
 
  
According to stoichiometry :
2 moles of  give = 2 moles of
 give = 2 moles of 
Thus 0.113 moles of  give =
 give = of
  of 
Thus 0.113 moles of NaCl are created as a result of decomposing 12 grams of  .
