answer the following questions that relate to the analysis of chemical compounds. a) A compound containing the elements C, H, N, and O is analyzed. When a 1.2359g sample is burned in excess oxygen, 2.241g of CO2(g) is formed. The combustion analysis also showed that the sample contained 0.0648g of H. i) determine the mass, in grams, of C in the 1.2359g sample of the compound. ii) when the compound is analyzed for N content only, the mass percent of N is found to be 28.84 percent. Determine the mass, in grams, of N in the original 1.2359g sample of the compound. iii) Determine the mass, in grams, of O in the original 1.2359g sample of the compound. iv) Determine the empirical formula of the compound.

Question

answer the following questions that relate to the analysis of chemical compounds.

a) A compound containing the elements C, H, N, and O is analyzed. When a 1.2359g sample is burned in excess oxygen, 2.241g of CO2(g) is formed. The combustion analysis also showed that the sample contained 0.0648g of H.

i) determine the mass, in grams, of C in the 1.2359g sample of the compound.

ii) when the compound is analyzed for N content only, the mass percent of N is found to be 28.84 percent. Determine the mass, in grams, of N in the original 1.2359g sample of the compound.

iii) Determine the mass, in grams, of O in the original 1.2359g sample of the compound.
