2) In an experiment to determine the molar mass of dichlorobenzens C6H4C12 using freezing point depression of solvent cyclohexane, a student uses 10 mL or cyclohexane (density 0.779 g/ ml) and obtains an average freezing point of 5.75 degrees Celsius. She graphically determines the new freezing point to be 2.8 degrees Celsius by setting equation of 2 lines equal to each other. What is her ATf? If she uses a total of 0.2301 grams of dichlorobenzene what is her calculated molecular weight for the solute? What is % error from actual molecular weight of solute? Is this a reasonable result?

Provided are spectra for a compound with molecular formula CgH100 Part A) Give the degrees of unsaturation Part B) Identify the peaks that are associated with specific bonds of the structure and list the corresponding functional groups that the specific bonds belong to. Re- create the example table below that organizes this information. Use the wavenumbers that are already labeled on the spectra. Example table: wavenumber (cm-1) Corresponding Bond Type Corresponding Functional Group C(sp3)-H N-H 2978 3300 Part C) Draw the structure and clearly indicate which hydrogens correspond to which signals in the HNMR spectrum ONLY. The signals are already labeled A-D on the HNMR spectrum. Match the hydrogen labeling (HA, HB, etc.) on your drawn structure to the signal labeling provided. 4300 3320-2872 2951 3006 3003 2001 alkyl amine 1613 1510 1000

Can you show us how to do number 8. ? Please see the attached pic.This is not a graded question as it is a practice question . I am 60 years old and helping my son prepare for the AP exam in a few months. We do questions at the back of the textbook by Zumdahl and Zumdahl
e) A typical person has about 200 mg of cholesterol per 100 mL of blood. If the total blood volume of an indiyidual is 5.0 L. how many grams of total blood cholesterol does the individual contain?

Tonya sold 160 sandwiches for $2.00 each. Each sandwich consisted of 4 oz of ham, two slices of bread, and mustard. She paid $3.00/lb for the ham, $0.60/loaf for the bread and used 8 jars of mustard at $0.50 each. How much profit did she make? Note: I attempted the problem, but it felt like I was going about it wrong. It’s for a chem class, but is there a less conveluded algebraic way to solve it? Or other method?
