1. A student makes a 100% glycerol stock solution. Design a scheme to dilute the stock to a 1:20 dilution.

2. We need to make 200 mL of a 0.1 aqueous glycerol solution. In the lab, we only have a dry glycerol powder, so you will need to make a 1.0M stock solution before you make the dilution. The molecular weight of glycerol is 92.08 g/mol.
hint: gen chem C1V1=C2V2

3. I have a stock solution of 20mM Tris-Cl in the lab. My procedyre calls for 5mL of 1mM Tris-Cl. How much of the 20mM Tris-Cl should I add to the water to achieve the final dilution factor?
