Explanation:
Answer: 25.8 g of
will be produced from the decomposition of 73.4 g of
Explanation:
To calculate the moles :

The balanced chemical reaction is:
According to stoichiometry :
2 moles of
produce = 3 moles of 
Thus 0.242 moles of will produce=
of 
Mass of
= 
Thus 25.8 g of
will be produced from the decomposition of 73.4 g of
