A tenfold serial dilution (dilution factor of 10). Note that at each step, the previously diluted solution provides 10% of the solution in the next step. Other dilution factors can be used, as well. This procedure can be used to produce an extremely dilute reagent, depending on how many dilution …

Rather than reaching for the formula and the calculator, let’s use the principles above. A 0.01 M solution is equivalent to 10 mM and contains 10 mmol/L or 10 mol/mL ( 5 mol in 0.5 mL. This 5 moles is now in a final volume of 20 mL ( 5 mol/20 mL ( 250 M or 0.25 mM.

K2Cr2O7 must be weighed out to make this solution? Dilution – process of adding more solvent to a solution. Moles of solute before dilution = Moles of solute after dilution. Example: What volume of 16M H2SO4 must be used to prepare 1.5L of a 0.10M . H2SO4 solution? Learning Check: Prepare 500.0mL of 1.00 M HC2H3O2 from a 17.5 M stock solution.

Making a working solution simply required diluting some volume of stock solution to the concentration needed. The working concentration of a solution is represented as 1X. A concentrated solution could be represented as 10X if it has 10 times the amount of solute per unit volume compared with the working solution. A 50X stock has 50 times the ...
