In a laboratory experiment, a 13.0 −mL−mL sample of KClKCl solution is poured into an evaporating dish with a mass of 22.30 gg . The combined mass of the evaporating dish and KClKCl solution is 40.20 gg . After heating, the evaporating dish and dry KClKCl have a combined mass of 28.77 g . what is the molarity of the KCl solution? |

1. The mass of an empty evaporating dish and watch glass is 62.549 g. After the addition of an unknown, the mass was 63.089 g. The evaporating dish and unknown were heated strongly for 10 minutes. After cooling, the mass of the evaporating dish and sample were found to be 62.928 g. A sample of the unknown was also submitted to a flame test, and found to produce a violet flame. Is the unknown NaHCO3, Na2CO3, KHCO3, or K2CO3? Explain...
