WebA compound contains only C , H, and N. Combustion of 35.0 mg of the compound produces 53 mg CO2 and 32.6 mg H20. What is the empirical formula of the compound? Expert's answer w (C/CO 2) = 12g/mol / 44g/mol = 0.2727. m (C) = w (C/CO 2) × m (CO2) = 0.2727 × 53 mg = 14.4545 mg. w (H/H 2 O) = 2g/mol / 18g/mol = 0.1111.
