How many moles of KCIO3 are needed to produce 3.6 moles of O2

Answer 1

Hello, Gabby,

We need to start with the reaction and developed a balanced equation. I'll presume it is the decomposition of

KClO₃ that we are using. I balanced this decomposition reaction:

2KClO₃ → 2KCl + 3O₂

This tells use we need 2 moles of KClO₃ to produce 3 moles of O_2, a molar ratio of (2 moles KClO₃/3 moles O₃). Multiply this ratio by the number of moles O₂ desired (3.6 moles O₂)

(2 moles KClO₃/3 moles O₃) (3.6 moles O₂) = 2.333 moles KClO₃
