A. You need to make a dilution of a stock solution of sodium chloride.

The stock solution on your shelf has a concentration of 1M. You need 100ml of a 0.1M dilution. Using C1V1 = C2V2, calculation how much stock solution and how much water you need to pipette to make your dilution.

B. You separate pigments A and B using paper chromatography.

• A travelled 4mm

• B travelled 2mm

• Solvent travelled 10mm

Calculate the Rf of pigments A and B.

You know the pigments have different solubility in the solvent. Which pigment (A or B) likely has higher solubility? Briefly explain why
