KClO₃ → Kelt Oz
cestrela7 [59]

Answer:

5.2 moles of  KClO₃  are needed

Explanation:

Given data:

Number of moles of potassium chlorate needed = ?

Number of moles of O₂ formed = 7.8 mol

Solution:

Chemical equation:

2KClO₃      →     2KCl + 3O₂

now we will compare the moles of KClO₃ and  O₂.

                   O₂        :         KClO₃    

                    3          :           2

                   7.8        :          2/3×7.8 = 5.2

5.2 moles of  KClO₃  are needed.

What would you multiply "grams of barium" by to get the units "moles of barium" ?
solmaris [256]
Moles = weight in grams / molecular weight.

So I would divide the "grams of barium" by its molecular weight (which is 137.3) to get "moles of barium". :)
