you have a stock solution of 300ppm of analyte under investigation. how much of that stock solution in mL do you need to prepare V2=247.2 mL of M2=143.3 ppm solution?

Expert Solution

Formula for dilution :

M₁ V₁ = M₂V₂

Concentration stock solution M₁ = 300ppm

Volume of stock solution V₁ = ? ( to be found)

Concentration of final solution M₂ = 143.3ppm

Volume of the final solution V₂ = 247.2mL

300ppm x V1 = 143.3ppm x 247.2mL

Let us divide both sides by 300ppm

The volume of stock solution needed to prepare 247.2mL of 143.3ppm solution is

118.1mL
