For preparing 5M NaCl solution, Since 1M is the molecular weight mass in grams one litre of solvent. Hence the molecular weight of NaCl is 58.44 g/mol. For 5M NaCl solution 58.44 * 5 = 292.2 g dissolved in 1 litre of distilled water.
For Preparing 5 litre solution with 1M Final NaCl concentration
M1V1 = M2V2, 5M * V1 = 5L * 1M (M1 = initial conc, M2 final conc, V1 required volume, V2 final volume to be made)
= 1 Litre of 5M NaCl solution to be mixed for making your required solution.
2. DNA replication is a cofactor for DNA polymerase, it facilitates the formation of nucleotide monophosphates from tri phosphates. Hence the insertion of correct nucleotide and further its conversion to monophosphate.

I need to prepare a 4M solution of NaCl. How would I do that? Then I'd need to use that solution to prepare some other 4L volume reagent with a final concentration of 1M NaCl. How would I make that? What is the role of magnesium in dna replication ?
You start with a 4M stock solution of NaCl, you need to make dilutions to obtain various working solutions. Describe how you would make 100 mL of a working solution that has a final concentration of 1M. Be sure to include the volume and concentration of the components.
You have a 1 M solution of NaCl. How much do you need to dilute to make 10 L of isotonic saline (0.9%)? Remember that the units of volume and concentration must be the same on both sides of the equation.
