Acompound containing the elements c, h, n, & o is analyzed. when a 1.2359 g sample is burned in excess oxygen, 2.241 g of co2(g) is formed. the combustion analysis also showed that the sample contained 0.0648 g of h.
(i) determine the mass, in grams, of c in the 1.2359 g sample
(ii) when the compound is analyzed for n content only, the mass percent of n is found to be 28.84%.
(iii) determine the mass, in grams, of o in the original 1.2359 g sample of the compound.
(iv) determine the empirical formula of the compound.
