Pheromones are compounds secreted by the females of many insect species to attract males. One of these compounds contains 80.78 percent C, 13.56 percent H, and 5.66 percent O. A solution of 1.00 g of this pheromone in 8.50 g of benzene freezes at 3.37°C. What is the molecular formula of the compound? What is the molar mass of the compound? (The normal freezing point of pure benzene is 5.50°C.) g/mol
