A compund containing the elements C, H, N, and O is analyzed.When a 1.2359g samole is burned in excess oxygem, 2.241 g ofCO2(g) is formed. The combustion analysis also showed that th sample contained 0.0648 g of H.
i) what is the mass, in grams, of C in the 1.2359 gsample of the compund?
ii) When the compund is analyzed for N content only, the masspercent of N is found to be 28.84 percent. What is the mass, ingrams, of N in the original 1.2359 g sample of the compound?
iii) What is the mass, in grams, of O in the original 1.2359 gsamole of the compound.
iv) What is the empirical formula of the compound?
