How many grams of oxygen can be produced from the decomposition of 100g of KClO3?

• Chemistry -

and can you please explain the process resulting with the answer (ie. formulas ect.) thank you.

• Chemistry -

how many moles of KClO3 do you have in 100 g.

2) balance the equation:

2KClO3>>2K + Cl2 + 3O2
so for every two moles of potassium chlorate, you get three moles of O2

3) take the moles of KClO3, multiply it by 3/2. That is the moles of KClO3. Convert it to grams.
