Question

Chem I. Dr. Hasher EXTRA CREDIT The organic compound MTBE (methyltertiary butylether) is used as a fuel additive that allows gasoline to burn more cleanly thus leading to a reduction in pollution. Recently, however, MTBE has been found in the drinking water of a number of communities. As a result several states are phasing out the use of MTBE as a fuel additive. A combustion experiment using 10.00 g of MTBE was found to produce 24.97g of CO and 12.26 g of H.O. (a) What is the empirical formula of MTBE assuming it contains C, H, and only? (b) The molar mass of MTBE was experimentally determined to be 88.1 g/mol. Using this information what is the molecular formula of MTBE Over
