Question

Complete combustion of an organic compound using the Dumas method yielded exactly 6 moles of $CO_2$, 4 moles of $H_2O$, and 1 mole of $N_2$ gas. Assuming the compound contains only C, H, and N, its empirical formula is:

Prashant Kotian · Accepted Answer

Correct answer: B. 6 moles of gives 6 C atoms. 4 moles of gives H atoms. 1 mole of gives N atoms. The molar ratio is C:H:N = 6:8:2. Thus, the empirical formula is .
