A cleaned, dried aluminum can (Cherry Pepsi) was recently weighed. The recorded mass was 13.2518 grams. Assuming that 0.5000 g of the weight was other materials (paint, aluminum oxide), what would the theoretical yield be (on a mass basis) if all of the aluminum in the can was converted into alum? Remember to report your result with the correct units and precision.
