From the reaction of 0.1000 g of solid granular tin with 0.1000 g of solid iodine in 3.0 mL of solvent methylcyclohexane (density = 0.770 g/mL) was isolated 0.0740 g of an iodide of tin as the sole product of the reaction. Recovered from the reaction mixture was 0.0747 g of unreacted granular tin. What was the empirical formula of the product? If there is some ambiguity in your answer, try using any resource you see fit to determine the most reasonable answer.
Suppose you add 4.25 g of naphthalene, C10H8, to 67.9 g of benzene, C6H6, and they form an ideal solution. The vapor pressure of pure benzene is 0.1252 atm at the temperature of the experiment.
