Prior to their phaseout in the 1980s, chemicals containing lead were commonly added to gasoline as anti-knocking agents. A 5.021 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 5.465 g CO, (g) and 2.796 g H, O(g).
Determine the empirical formula of the gasoline additive.
