The crucible is not fired, as the procedure suggests, but had retained some impurities from previous use (or it could only be oily smudges from fingers). the mass of the "dirty" crucible is recorded. however, the impurities are burned off in the experiment. will the reported mass of the final product be too high, too low, or unchanged as a result of this technique error? explain.
