given the balanced equation:
What is the total number of moles of O2 that are produced when 8.0 mol of Al2O3(s)are totally decomposed ?
please help me.

From the equation 2 moles of Al2O3 yields 3 moles of O2
From the equation 4 moles of Al2O3 yields 6 moles of O2
From the equation 8 moles of Al2O3 yields ?? moles of O2

so the answer is 2 moles ?

i meant 12* moles

Are you just guessing? Which answer are you going for and why?

It's 12 moles. Cross multiply 8x6= 48, and then 48/4= 12
