We are working in a lab and need a 38% concentration of C12H22O11. However, we have solutions with a concentration of 20% and 60%. How much of each do we use if we need 50 mL of the 38% concentration? (Hint: You will want to find an equation for the amount of each solution to use and another for the amount of C12H22O11.)

1)You are given a protein solution with a concentration of 0.15 mg/ml. We need 10 µg for an experiment. What volume of the protein solution do we need? My answer: Convert 0.15 mg/ml to μg/ μl and you will get 150 μg/ μl. C = M/V rearrange for Volume V= M/C , V= (10 μg)/(150 μg/ μl) = 0.06667 μg/ μl 2) Suppose we want to prepare a solution containing 100 µg of the protein at a concentration of 1...

For this problem, I need to create a step by step process in order to determine all of these things in a lab. I understand how to create the 50 ml of each concentration by calculating mols from mol= MV, and then adding water. What I do not understand is how to isolate the product and turn it in to an anhydrous salt. (Maybe vaccum filtration?) I also need to be able to find the concentration from the supernatant. Create...

you need to prepare a buffer solution with a ph of 7.8. A lab mate tells you to use N-2- hydroxyethylpiperazine-N'-2-ethanesulfonic acid(HEPES), a sulfonic acid with a pka of 7.5. since you know that the buffer pka should be close to the desired pH, this sounds good. You make the solution according to the following recipe, which is supposed to make 600 ml of a 0.5 M solution: dissolve 0.2 moles of HEPES in 400 ml of water. add 0.1...

You want to have $2.5 million in real dollars (HINT: it means we need to use the real interest rate in the calculation) in an account when you retire in 40 years. The nominal return on your investment is 10.3% and the inflation rate is 3.7% (HINT: do not use the approximation when finding the real interest rate). What real amount must you deposit each year to achieve your goal? Can anyone solve this without using excel formulas? Thanks!

I am asked to prepare a bradford assay in class using gamma-globulin (to determine the concentration of protein (a-La in original milk and multiple other samples) in order to do this I must prepare a strand curve (calibration curve) with samples containing known concentrations of gamma-globulin. The dilutions are made with a buffer A used in lab and the final volume of each dilution must be at least 200 uL. The standard curve will range from 0 to 60 mg/mL...
