Answer
4 Al + 3 O2 -> 2 Al2O3
309 g Al and 274 O2
Work Step by Step
First balance oxygen with a coefficient of 3 on the left side and a coefficient of 2 on the right side. Then balance aluminum with a coefficient of 4 on the left side. All atoms are now balanced.
Use molar masses and a mole ratio as conversion factors to compute the mass of aluminum required.
