Question 15 1 Point Ferrocene, [Fe(CHX)molar mass 186.03 g/mol)can be prepared by reacting 6.0 g of FeCl (s) (molar mass -126.75 g/mol) with 4.8 g of cyclopentadiene (CsHall): molar mass 66.01 g/moljand an excess of KOH, as shown in the following reaction FeCl2 + 2C5H6 + 2KOH -- FeC10H10 + 2H20 A student who carried out this reaction obtained 2.7 g of ferrocene. Of the following choices which has three correct answers? A FeCl, is limiting: 4.2 g of ferrocene could be theoretically formed; obtained 54.6 % yield FeCl, is limiting: 4.2 g of ferrocene could be theoretically formed; obtained 89.4 % yield CH is limiting: 0.0151 g of ferrocene could be theoretically formed; obtained 74.8 % yield OCH is limiting: 6.76 g of ferrocene could be theoretically formed; obtained 39.9% yield 1 Point Question 16 The density of water is 1.00 g/mL at 4"C.How many water molecules are present in 2.66 ml of water at this temperature? 6,56 X 102 molecules B 5.59 X 10 23 molecules 4.89 X 10 22 molecules D 8.90 X 10 22 molecules
