Answer: 0.99 grams of chlorine gas is produced by the reaction of 3.3g of ammonium perchlorate
Explanation:
To calculate the moles, we use the equation:
The decomposition of ammonium perchlorate is :
According to stoichiometry :
2 moles of 
produce = 1 mole of 
Thus 0.028 moles of produce=
of
Mass of 
Thus 0.99 grams of chlorine gas is produced by the reaction of 3.3g of ammonium perchlorate
