7. A 0.5 gram sample of hoodia gordonii isolated from natural sources yields an observed rotation of -0.76° when dissolved in 20 mL of chloroform and placed in a 1-dm cell. Determine the specific rotation [α] of hoodia gordonii for: (a) the entities as defined above,(b) an increase in solute from 0.5g to 1.0 g;(c) an increase in solvent from 20 mL to 40 mL; and (d) an increase in path length from 1 dm to 2 dm. Does entities defined above refer to the picture since its a hoodia gordnii? I don't even know where to start with this one
