A compound containing only C, H, and O is massed (0.01068 g) and then combusted to yield CO2 (0.01601 g) and water (0.00437 g). The molar mass of the substance is 176.1 g/mol. a. Determine the empirical and molecular formulas. b. Using the molecular formula, write out and balance its combustion reaction, assuming CO2 and water vapor are the only products produced.
