Prior to their phaseout in the 1980s, chemicals containing lead were commonly added to gasoline as anti‑knocking agents. A 2.073 g sample of one such additive containing only lead, carbon, and hydrogen was burned in an oxygen‑rich environment. The products of the combustion were 2.256 g CO 2 ( g ) and 1.155 g H 2 O ( g ) . Determine the empirical formula of the gasoline additive.
