Answer: 633.6 g of 
can be produced from the decomposition of 4.8 moles of 
Explanation:
The balanced chemical equation for decomposition of 
is :
According to stoichiometry :
1 mole of produce = 3 moles of
Thus 4.8 moles of will rproduce=
of
Mass of 
Thus 633.6 g of can be produced from the decomposition of 4.8 moles of
Answer:
Molarity = 5.22 M
Explanation:
Given data:
Mass of sodium chloride = 7.0 g
Volume of solution = 23.0 mL ( 23.0/1000 = 0.023 L)
Molarity = ?
Solution;
Number of moles of NaCl = 7.0 g/ 58.4 g/mol
Number of moles of NaCl = 0.12 mol
Molarity = moles of solute / volume in litter
Molarity = 0.12 mol / 0.023 L
Molarity = 5.22 M
