Calculate the empirical formula of the hydrocarbon.14. (10 points) Calculate the atomic weight of element X given that 2.33 x 1014 atoms ofX have a mass of 4.59 x 1016 amu. What is the identity of X? ______15. (20 points) A person’s blood alcohol (C2H6O) by titrating a sample of blood plasma(that’s blood that’s had its cells removed) with a potassium dichromate solution. Thenet ionic equation is:16 H+ + 2 Cr2O7 2- + C2H6O 4 Cr+3 + 2 CO2 + 11 H2OIf 35.46 mL of 0.05961 M Cr2O7 2- is required to titrate 28.00 g of plasma, what is themass percent of alcohol in the blood? What is the molarity of ethanol in the sample?If a normal person has a total blood volume of 10 pints, how many 12 oz. beers didthis person drink prior to the blood test? [1 fluid ounce = 29.6 mL, 1 quart = 2pints] (Assume beer is 5% alcohol by volume.)16. (5 points) Two of my musician friends were studying in Hungary. They wanted to buya turkey for Thanksgiving but turkey is not a common food item there. They finallytracked down a butcher who promised them a live turkey, but he wanted to knowwhat weight. Neither of them had taken this Chemistry course, so they couldn’t dothe English/metric conversion. After a long debate, they decided to order a 15 kgturkey. Did they have lots of
