Question

A 3.0 mole sample of KBrOz was decomposed according to the following

equation. How many moles of O2 are formed? *
2KBrO3 → 2KBr + 302

Answer 1

Step-by-step explanation:

2KBrO₃ => 2KBr + 3O₂

3.0 mol KBrO₃ => 3/2 x (3 mole O₂) = 4.5 mole O₂*

*Ratio of moles must produce a larger number of moles for Oxy than KBrO₃.
