A stock solution of 5 M sodium acetate has been made. You want to make a 50 ml 0.33 M sodium acetate solution for your lab bench. How much of the stock solution and water do you need? (ml)
concentration of stock M1= 5 M
concentration needed M2= 0.33 M
the volume of the stock needed V1=?
final volume V2=50 mL
M1V1=M2V2
V1=M2V2/M1
=0.33 50/ 5
= 3.3 mL
so volume of the stock required= 3.3 mL
volume of water required= 50-3.3=46.7 mL
