Chapter 12 - Stoichiometry - 12.2 Chemical Calculations - 12.2 Lesson Check - Page 398: 25

Stoichiometry is all about the ratio of moles of one substance compared to the moles of another substance. Since it is how the moles compare, one must know how much of each substance there is, which is impossible without balancing the original equation to tell you how much substance the reaction forms.
