Determine the weight/volume of the chemicals needed to prepare the following solutions:

a) 100 ml of 0.9% (w/v) saline (NaCl)

b)  30 ml of 50% glycerol (v/v)

c) Electrophoresis requires TAE, which is a specific mixture of Tris base, acetic acid, and EDTA. TAE is normally made as a 50X concentrated stock. Provide a recipe to make 40 ml of 50X TAE.

The recipe for one liter of 50X TAE is as follows:
242g Tris base, 57.1 ml glacial acetic acid, 100 ml 0.5 M EDTA
