In art of the Ancient Near East (Assyrian Art), sculptures often had carved eyes accented with shells set in bitumen, a black tar-like substance. Chemical analysis of bitumen by using a combustion reaction yields 6.575 g CO2 and 1.346 g H2O.
a. What is the empirical formula for bitumen (CxHy)?
b. The molecular weight of CxHy is 78.1134. What is molecular formula?
