#3 * 10^(-2)# mols #Al_2O_3#

Explanation:

By looking at the reaction coefficients in the balanced chemical equation, we see that 2 moles of #Al# will form one mole of #Al_2O_3#.

#mols Al_2O_3 = (mols Al)/2#

#mols Al_2O_3 = 0.03#

Since you have one sig fig, the answer would be:

#mols Al_2O_3 = 3 * 10^(-2)#
