Question

Given a stock standard solution of concentration 0.200 M, calculate the volume in mL required to make up calibration standards of the following concentrations (in 25.0 mL volumetric flasks)

1.60 x 10-2 M .....mL

Answer 1

M1V1 = M2V2

.200 (.025) = 1.60 X 10 -2 (V2)

V2 = .315 L

1.60 x 10-2 M in 315 mL
