A method for recycling scrap aluminum converts it to alum [potassium aluminum sulfate dodecahydrate, KAl(SO4)2·12H2O].
What is the maximum amount of alum (in metric tons) that can be prepared from 3.12 metric tons of scrap aluminum (1 metric ton = 1000 kg)?
This is a simple stoichiometry problem. Here is a worked example of one. Just follow the steps.
