I am trying to find x, which is the protein in mg. I know why will represent absorption. What will i put for m and b for my values? I know one axis is y for absorbance, i don't know what other values to put in for the rest of the graph.
Note: a Unit is ((ΔA/Δmin)/(6220 M -1 cm -1)) X 106 μM/M X 3 X 10-3 L
by the way, this question is different from the previous question i asked.
sorry, just realized i left the density out. The density is 1.049 g/mL. This should help. Thanks.
I have to use molecular weight (60 g/mol) to convert 0.058 M (58nM) to mL. my instructor wrote (M to moles to grams to mL). The answer is 3.34mL I just need to know how to get there.
okay. Here is the first acid and base worked out. Acetate(base): .3797 grams Acetic acid(acid): .1674 grams Are these right? If they are, i can finish the rest. Thanks.
I noticed some mistakes in my conversions. The answer I got for acetate was 37.97 grams. For CAPS, i got.112 grams. Are these correct? Thanks.
By the way, I have been using a pH of 7 for all of them.
Okay, I have worked out the first two. Am I doing them right? For acetate, I got 27.9 grams. For CAPS, I got 5.08 grams. Am I doing these right?
okay, let me just stick to the pre-lab question using the table. Here is the pre-lab question: Calculate the weight of the buffers you will use to make the buffers for part A for all the buffer possibilities listed under procedures in part A, stp i. In
these are pre-lab questions, so i haven't been given a ph yet. These are questions due before lab starts.
okay, this is what I have so far and now don't know how to finish. I used TRIS. pH=8.30+log(121.1/157.6) pH=8.19 Note: TRIS (Trizma base) MW= 121.1 TRIS-HCL MW= 157.6 (I hope I am using the correct things) After I got the pH, I got stuck on how to finish
which buffer do I choose? There are instructions above the table does this have anything to do with my choice for the problem i am working out, or do I just pick whatever one I want and do the math? Above the table it states, Make two buffers starting with
