Red cabbage anthocyanin extraction 1. Weight of red cabbage is 1438 g. What is the volume of acidified methanol needed to fulfil the ratio 1:1? (Use the formula of density =; mass volume 2. For a weight of X sample, what is the corresponding volume of methanol needed to| achieve a ratio of 1:1 during maceration? X= 293.15 g 3. In the liquid-liquid extraction, there are two funnels with solutions of total volume 250 mL and 500 mL respectively. Using the ratio of 1 part of aqueous to 3 parts of ethyl acetate for liquid-liquid extraction, how much of ethyl acetate is needed for each funnel?
