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?
