An unknown element, X, combines with chlorine to give a substance with the formula
XC14. A chlorine analysis of the substance indicates that it contains 83.47% chlorine by mass.
What element is X and what is the formula of this compound?
(Hint: to identify an element or compound, identify its molar mass. Remember that Molar Mass
= (grams A)/(moles A). Solve for each individually and then divide them to find molar mass.)

- The organic compound MTBE (methyltertiarybutylether) 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 CO2 and 12.26 g of H2O. (a) What is the empirical formula of MTBE assuming it contains C, H, and O only?
