A calorimeter consists of an aluminum cup inside of an insulated container. The cup is weighed on a top-loading balance and is found to have a mass of 42.69 g. A reaction is conducted in the calorimeter, raising the temperature from 20.00°C to 26.41°C. What is the change in heat, q, for the aluminum cup, in units of J? Aluminum has a specific heat of 0.903 Jg-1°C-1

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.
