Answer:
12.3 mo
Explanation:
Given the following balanced chemical equation, 2 NaClO3 → 2 NaCl + 3 O2, how many moles of O2 will be produced from 8.21 moles of NaClO3?
for every 2 moles of NaClO3, you produce 3 moles of O2.
so for O2 you produce 3/2 the moles of NaClO3
so 8.21 moles of NaClO3 will produce 8.21 X 3/2 moles of O2
=12.3 mole
