1. You have:

a 0.25M stock solution of NaCl (Formula Weight: 58.4g/mole),

a 0.5M stock solution of glucose (Formula Weight; 180.2g/mole),

and a bottle of solid Tris base (Formula Weight: 121.1g/mole).

How would prepare (be specific) 500mL of a single solution containing 500mM Tris, 25mM glucose, and 5mM NaCl.

2. Describe how you would prepare 50mL of a 0.250M stock solution of potassium chloride (Formula Weight: 74.55g/mole). Using this stock solution, describe how you would prepare 100mL of the following dilutions: 5mM and 2500mM.
