Im having trouble with the moles steps. I know there's 3 steps, I need help with step to moles to moles.

Question: If 12 moles of Al2O3 are produced, how many moles of aluminum reacted?

Write the equation!

Al ---> Al2O3 (we don't need to include the O2 to facilitate your understanding)

When the Al is balanced, 2Al ---> Al2O3

You see that 2 moles of Al will form 1 mole of Al2O3. So, can you do it now?

Rate my answer if you don't mind:)
