3% x 1/200= 0.015% C1V1=C2V2 C1= original concentration =3% C2 =concentration of diluted solution (0.015%) V2=volume of diluted solution=6oz (3) (V1)=(0.015) 6oz (3) (V1)=(0.015) (6oz) /3=0.030 oz 0.030 x (29.5mL/1fl oz) =0.89 mL The making of a solution of a given percentage strength is a simple matter where both the substance and solvent are weighed, the preparation of a definite volume of a solution of a given percentage of strength is the way to calculate how many milliliters and the solution.
