How many grams of oxygen are produced in the decomposition of 5.00g of potassium chlorate?

KClO3(s)--->KCl(s)+O2(g)
[the equation may not be balanced]

My answer is 1.96 g of O2.

The balanced equation is
2KClO3 ==> 2KCl + 3O2

I, too, obtained 1.96g O2. You must have balanced the equation before solving, else our answers would not have agreed.

Yes, I did. Thank you!
