Problem- Prior to their phase-out in the 1980s, chemicals containing lead were commonly added to gasoline as anti-knocking agents. A 7.165 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 7.799 g of CO2(g) and 3.990 g of H2O(g). Insert subscripts below to appropriately display the empirical formula of the gasoline additive
