1. Caproic acid, which is responsible for the foul odor of dirty socks, is composed on C, H, and O atoms. Combustion of a 0.225 g sample of this acid produces 0.512 g CO₂ and 0.209 g H₂O. a. What is the empirical formula of caproic acid? b. If caproic acid from part a (above) has a molar mass of 116 g/mol, what is its molecular formula? 2. A 0.250 g sample of hydrocarbon undergoes complete combustion to produce 0.845 g of CO2 and 0.173 g of H₂O. What is the empirical formula of this compound? 3. Cupric chloride, CuCl2, when heated to 100°C is dehydrated. If 0.235 g of CuCl2 x H₂O gives 0.185 g of CuCl2 on heating, what is the value of x? A 0.2500 g sample of a compound known to contain carbon, hydrogen and oxygen undergoe complete combustion to produce 0.3664 g of CO2 and 0.1500 g of H₂O. What is the empirica formula of this compound?
