A natural product was isolated in the laboratory, and its observed rotation was +10° when measured in a 1 dm sample tube containing 1.0 g of compound in 10 mL of H₂O.What is the specific rotation of this compound?

The specific rotation [α] is calculated using the formula [α] = α_obs / (l * c), where α_obs is the observed rotation, l is the path length in decimeters, and c is the concentration in g/mL. Here, α_obs = +10°, l = 1 dm, and c = 1.0 g/10 mL = 0.1 g/mL. So, [α] = +10° / (1 * 0.1) = +100°.
