6. You are taking a lab course with Professor Girard in cell biology at a local community college and need to prepare 50ml of a 50% ethanol and 1% acetic acid fixative. How much ethanol and how much acetic acid will you need? Both are liquids. How much water do you need to add?
7. Professor Valm studies the oral microbiome of humans and you join his lab for undergraduate research. To isolate oral bacteria, you have to prepare a brain heart infusion broth supplemented with 10μg/ml of NAD and 5 μg/ml hemin (μg stands for microgram). If you make 800 ml of the broth what percent (weight/volume) is each in the final solution?

Lab : Aldol Condensation Purpose. In this lab you will conduct the Aldol condensation reaction under solid-state reaction conditions that will involve grinding reactants in the solid phase. You must read ahead and learn about this reaction and the chemical mechanism for the Aldol condensation. There are two possible products which are the initial Aldol or subsequent elimination product. You will need to isolate and purify your reaction product. You will use your melting point, IR, 1H and 13C NMR spectra to...

I need to make (yeast fermentation) lab
report.
This is the lab experiment and results:
This is a guide to making the lab report:
General Biology BIO121 Yeast Fermentation Lab Introduction Organisms stay alive by the utilization of energy through metabolism. The energy acquiring pathways in photosynthesis convert radiant energy from the sun into the chemical bond energy of carbohydrates. This photosynthetic process is limited to the producers or autotrophs, which include plants, photosynthetic bacteria and some protists....

Need help filling in my data sheet from a lab. My professor said
the pressure was 24.6 inches of Hg and that we needed to convert
that to moles. Im not sure i put that in the correct spot. I
included the lab protocol. Plz plz plz help me fill in the blanks
and let me know if i did something wrong Im very confused haha.
THANKS!!

Lab 8: Exercises EXERCISE 8.1 GM is a 20 y/o male who was admitted to the ICU for severe closed head injury and multiple fractures resulting from a fighting engagement at the bar on his birthday. According to his friends, his Ht is 178 cm. His measured Wt at admission is 76 kg. His lab values were normal except for low Hgb and Hct due to bleeding (which was well controlled). He was unconscious, thus was tube fed for one...

please answer all parts I am trying to check my
answers.
Recrystallization of Acetanilide Recrystallization is an important method used by chemists to purify solid compounds. When a chemist conducts a chemical reaction as shown in Scheme 1, it will rarely go to 100% completion, and will frequently produce byproducts. These byproducts and some of the unreacted starting materials will be present in the end as impurities. Chemists need ways to remove these unwanted impurities so they can isolate their...
