Because of its detrimental effect on the environment, the lead compound described in Problem 3.138 has been replaced in recent years by methyl tert -butyl ether (a compound of C, H, and O) to enhance the performance of gasoline. (As of 1999, this compound is also being phased out because of its contamination of drinking water.) When 12.1 g of the compound are burned in an apparatus like the one shown in Figure 3.6, 30.2 g of CO2 and 14.8 g of H2O are formed. What is the empirical formula of the compound?
