How would I find the percent of P2O5 present in a sample of KH2PO4? I know that phosphorus is 22.761% by mass of KH2PO4. I weighed out 0.422g of KH2PO4, then filtered it with water. Then I added 10 mL of 0.4 M MgSO4 to the filtrate. Then I added 1 mL of 6 M NH3 slowly with a disposable pipet while stirring. Then I touched the stirring rod to red litmus paper. Then I continued adding 1 mL NH3...

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...
