- Give your solution pleaseOn a paper, draw a schematic diagram on the Extraction of Flavonoids using the procedures stated below. Procedure: Extraction of Flavonoids Weigh 10 g of the shade dried plant sample and chop into small pieces. Macerate with 200 mL 70% ethanol for 3 days at room temperature (25°C). Filter the extracts in vacuum using Whatman filter. Evaporate to dryness. Weigh the residue and compute the percentage yield.If the agar instructions say to mix 50 grams of agar in 1 liter of water, how many grams of agar would you mix into 100 milliliters of water to get the proper concentration of agar?
- The lab provides you with 25 mg/ 100 mL of BAP stock solution. You only need 1 mg of BAP in 180 mL of media. Thus, how much BAP stock solution will you pipette into 200 mL plant tissue culture media.?Give correct detailed Solution..I will give you upvoteA researcher wishes to obtain a glycoside (an organic compound) from an aqueous plant extract using the solvent extraction technique. She therefore performs the following steps: Step 1: An aqueous solution (100 mL) containing 7 g of the glycoside was shaken with 50 mL of ethyl acetate. Step 2: The resulting aqueous layer from Step 1 was further shaken with 50 mL of dichloromethane. Given that: Kp for the glycoside in ethyl acetate-water = 0.8 Kp for the glycoside in dichloromethane-water = 0.9 Calculate the total mass of glycoside extracted. If the molar mass of the glycoside = 784.3 g/mol, calculate the molar concentration of the glycoside remaining in the aqueous layer after each extraction.
