Use stock solution of 0.5 M CuSO4 to make up the following solutions by serial dilution to a final volume of 1 ml: 50mM, 5mM, 0.5mM, and 0.05mM Please show 'how many DI water 0.5M CuSO4 needed to be used?'
Question 6 Using stock solutions to make up a solution: from final concentration to volume You need to digest a sample of DNA with a restriction enzyme. You will do this reaction later in the semester. The buffer for this reaction has a final concentration of 40 mM Tris, pH 7.5, 10 mM MgCl2 and 50 mM KCl. You have the following stock solutions: 0.5 M Tris, pH 7.5, 1 M MgCl2 and 2 M KCl. How would you make...

1, Serial dilution Questions: a) (5 pts) Suppose you begin with stock solution of dye that has a concentration of 350.0 mg/L and do the following set of serial dilutions on it: 5.00 mL of stock diluted to a total volume (TV) of 500.00 mL (Dilution 1); 2,00 mL of Dilution 1 is then diluted to a TV of 250.00 mL (Dilution 2); finally, 1.00 mL of Dilution 2 is then diluted to a total volume of...
You will calculate the concentration of NaF in the beaker corresponding to each of the four aliquots of standard in the next four questions. See illustration on page 47 in the lab manual for a demonstration of this procedure. Calculate the concentration (M) of NaF in the beaker initially filled with 20 mL TISAB/DIW after the first aliquot of standard stock is added (following 1:1 dilution with TISAB). Standard stock solution concentration (before dilution with TISAB): 0.11 M Total volume...
