Obtain the mass of the wet alum. You will need to have about 2 g of wet alum (3 g if the mass includes the filter paper) so that you will have enough for the next two weeks. If you don’t have enough, collect the second crop of crystals and/or redo the synthesis.

We measure the success of our synthesis by the PERCENT YIELD. The percent yield is defined as the percent of the maximum weight of product that could be obtained represented by what is actually obtained. I.e., ... From its formula, 1 mole of alum contains 1 mole of aluminum. If we begin with 37 mmol of Aluminum, we can make...
