Question

If 2.2 moles of calcium oxide are decomposed, how many moles of oxygen are produced?
2CaO --> 2Ca + O2

Answer 1

Our chemical reaction tells us the molar ratio of reactants and products

For every 2 moles of CaO, we will produce 2 moles of Ca and 1 mole of O2

The ratio between CaO and O2 is 2:1

So if you have 2.2 moles of calcium oxide (CaO), how many moles of oxygen would you make?

Answer 2

(just divide by 2, it's that easy)

Answer 3

yes thxx

Answer 4

Of course!
