During the liquid-liquid extraction of your panacetin sample, the dissolve acetylsalicylic acid (aspirin) will be in which layer

Panacetin is a mixture of three components: sucrose, aspirin and tylenol. To determine the arrangement of layers, you must research on the densities of the components. The densities of sucrose, aspirin, and tylenol are 1.59 g/mL, 1.4 g/mL and 1.26 g/mL. The more dense the component, the farther it sinks to the bottom. Thus, the topmost layer is tylenol, followed by aspirin, and the bottom layer is sucrose. Therefore, aspirin is placed in the second layer.
