A researcher needs 80 mL of an albumin solution at a concentration of 4 mg/mL. She uses a stock solution of albumin at 20 mg/mL and mixes it with water. How many mL of water and stock solution should be mixed?
Homework Answers
Normality is defined as gram equivalent of solute in a given volume of liquid (solution).
Therefore, 1 g/L = 1 mg/mL
Thus, we can use the Is the C1 x V1 = C2 x V2 formula.
C1 : Is the initial concentration of solution, =20 mg/mL
C2 : Is the final concentration of solution, = 4 mg/mL
V1: Is the initial volume of solution, to be found out = X
V2 :Is the final volume of solution, 80 mL.
Thus, 20 x X = 4 x 80
Therefore, X = 4 x 80
20
X = 16 mL
