You go to the lab to run this experiment. Your lab partner found an old book which had a procedure (just like Harry Potter found the Half Blood prince’s book in book 6). Some general ideas are given but some ink on some details had faded out . The following questions will help you complete the picture. 1. Mix 5 mL 1-phenyl ethanol (molar mass 122 g/mol, density =1.02 g/ml) with 15 mL of conc. H2SO4 in a ______mL round bottom flask.2. Add a boiling chip and gently swirl the contents and heat to boil in a reflux set up for 60 minutes .3. Cool and collect the organic layer. Add CaCl2 was added. Stopper the flask and allow to stand for 10 minutes with occasional stirring.4. Decant the product in a pre-weighed product bottle. Weigh the product and calculate the % yield.Analyze the product using GC, IR, NMR and chemical test. What size RB flask should you pick for your reflux set up ?

When running the reaction, the starting material was found to be a liquid. Per the reaction procedure, you need 5.000 g of the material . You have an analytical balance, a micropipettor, a 100 mL measuring cylinder, a disposable plastic pipet (Berol pipet) at your convenience. What are some methods to get the amount that you need in the flask ?
