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:
According to stoichiometry :
2 moles of give = 2 moles of 
Thus 0.113 moles of give =
of
Thus 0.113 moles of NaCl are created as a result of decomposing 12 grams of .
