"Aluminum satellite dishes resist corrosion because aluminum reacts with oxygen gas (02) to form a coating of
aluminum oxide (Al203) according to the following chemical equation:
4Al(s)+ 30 2(g) → 2Al203(s)

In CER form:

What is the mass of 9.45 moles of Al203?

After correctly solving for the molar mass of Alz°3, Jacob set up the following conversion:
