A mixture of two hydrocarbons, C8H18 (octane) and C7H8 (toluene), has a mass of 183 g. The hydrocarbon mixture is burned in excess oxygen to form a mixture of carbon dioxide and water that contains 1.44 times as many moles of carbon dioxide as water. Find the masses of C8H18 and C7H8 in the mixture. g
