Problem 7 is analyzed using combustion a alysis. When 6.22 g of the inknown is urned,...
A 7.39 g sample of a compound containing C, H, and O is analyzed using combustion analysis. In a separate experiment, the molecular mass of the compound is found to be 300.44 g. The combustion analysis produces 21.63 g CO2 and 6.2 g H2O. A.How many grams of carbon were in the original sample? a)2.45g b)11.8g c)5.9g B.How many grams of hydrogen were in the original sample? a) .69g b).75g c).82g C.How many grams of oxygen were in the sample?...
A compound contains only carbon, hydrogen, and oxygen. Combustion of 18.92 g of the compound yields 27.73 g of CO2 and 11.35 g of H2O. The molar mass of the compound is 90.078 g/mol. *Each part of this problem should be submitted separately to avoid losing your work* 1.
