Hemlock contains a number of toxins, one of which is coniine.In a combustion experiment, 2.0000 g coniine was burned in excess oxygen to give 5.5343 g CO₂ and 2.4080 g H₂O.In a second experiment, it was determined that the compound is composed of only carbon, hydrogen, and nitrogen and its molar mass is less than 200 g/mol.Using the empirical formula of coniine, indicate how many atoms are in one molecule.For example, if the molecular formula were CNH₂, you would respond 4.

The empirical formula of coniine is C8H17N. The molecular formula is the same as the empirical formula since the molar mass is less than 200 g/mol. Therefore, the number of atoms in one molecule is 8 (C) + 17 (H) + 1 (N) = 26.
