Grant found the mass of an empty crucible and lid to be 62.549 g. After he
added an unknown, the mass was 63.089 g. The crucible and lid and unknown were
heated strongly for 10 minutes. After cooling, the mass of the crucible and lid and sample
were found to be 62.928 g. Grant also performed a flame test on a sample of his unknown,
and found it produced a violet flame. Is the unknown NaHCO3, Na2CO3, KHCO3, or K2CO3?
