For the same reaction,  what is the theoretical yield in grams  ? 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.
