How do you prepare a 6 mM solution of zinc chloride in 0.1 M MOPS buffer?...
How do you prepare a 6 mM solution of zinc chloride in 0.1 M MOPS buffer? How do you know how much buffer to put in the solution for the desired final concentration? Same question for preparing a 0.4 mM solution of a peptide with molecular weight of 1565.8 g/mol in 0.1 M MOPS? I dont understand how the buffer can have a different concentration than final solution but be used to make the solution?
Homework Answers
In this question you need two solutions, 0.1 M MOPS and 6 mM ZnCl.
So, in distilled water you will add MOPS and ZnCl according to the required weight.
Similarly, you can prepare the other solution. Instead of ZnCl, take 0.4 mM of peptide.
If you have any doubt then you can ask me in the comment section.

Your supervisor asks you to prepare 474.00 mL of ammonium buffer solution 0.1 M with pH= 9.00, from a concentrated ammonia solution (16%w/w, d=0.98g/mL) and solid ammonium chloride (97% w/w). (MW of NH3 = 17.031 g/mol and FW of NH4Cl = 53.491 g/mol and pKa NH4+/NH3 =9.24). How many grams of the solid ammonium chloride do you need? Consider two decimal places for the answer.

Question 7 Working with buffers You need 100 ml of 120 mM phosphate buffer and you have two stock solutions from which you can make the buffer; 0.6 M NaH2PO4 (the acid form) and 0.6 M Na2HP04 (the base form). You need to add 3 times more of the base form than the acid form to achieve the desired pH. How will you make this solution? Question 8...
